Weed Withdrawal

Vivid Dreams Are Common After Quitting Weed

By January 3, 2022June 29th, 202234 Comments

While sleeping, the brain is quite active – dreaming. Our dreams can be scary, realistic, or even fantastical. Sometimes, we wake up and have no idea that we’ve dreamed, while other times, we can recall our dreams because they were so intense. These dreams are known as vivid dreams.

Why do vivid dreams occur after you quit weed?

When quitting weed after prolonged use, many former users report vivid and intense dreams. Some users report dreaming all night. To understand the reasons why, we need to understand sleep cycles first.

During sleep, you go through four or five sleep cycles, each lasting for about 90 minutes. Among these cycles, one is known as rapid eye movement (REM) sleep whereas the others are known as non-REM sleep. Approximately 80% of dreams happen during REM sleep.

Studies have shown that acute exposure to marijuana suppresses REM sleep whereas it increases slow-wave or non-REM sleep. REM sleep is suppressed upon activation of cannabinoid receptor 1 (CB1) (Lovinger DM, Front Mol Neurosci., 2020). Because of this, many regular weed smokers don’t remember their dreams.

When chronic marijuana users quit, their dreams can become more intense because of REM rebound. REM rebound is characterized by an increase in REM sleep after periods of little REM sleep. Increased REM sleep can result in longer and more intense dreams.

How common are vivid dreams in former heavy users? How long do they last?

Sleep difficulty is reported by about half of former marijuana who often report insomnia, vivid dreams, and night sweats. Vivid dreams typically begin a week after quitting and can last for a month before tapering off. However, some former users report having vivid dreams for a year or more (Livine, Drug Alc Depend, 2019).

Sleep studies of people in the first week of marijuana withdrawal have shown changes in almost every phase of sleep, including longer time to fall asleep, decreased total sleep time, poorer sleep efficiency, and, as mentioned, increased time in REM sleep (Gates, Subst Abus, 2016Garcia, Am J Addict, 2015).

Most heavy marijuana users experience at least one withdrawal symptom after quitting weed and many experience more than one symptom. The number of symptoms is significantly associated with the frequency and duration of marijuana use prior to quitting.

There is light at the end of the tunnel!

Vivid dreams can be unpleasant and may impact sleep quality, leaving you feeling drained even after a full night of sleep. Take comfort in knowing that withdrawal symptoms from marijuana are challenging but do not last forever. If you find yourself still struggling with poor quality sleep weeks to months after you’ve stopped using marijuana, just find comfort in the fact that this is still normal, and part of the process.

Would you mind answering a few questions (anonymously)?

Currently, little data exists on sleep difficulty and marijuana use. is collaborating with researchers to explore this topic and others. We have created a short, anonymous survey which we will use to focus our future research efforts.

Your participation is appreciated and completely anonymous. You may skip any questions that make you feel uncomfortable and you are free to withdraw at any time.

About is a free, web-based resource and community created by a team of healthcare professionals and researchers. We distill the facts about marijuana use and its effects into practical guidance for interested persons or for those who are thinking about or struggling to quit weed. Finding reliable, easy to understand information about marijuana should never be a struggle—that is why our core mission is to provide the most up to date information about marijuana use, abuse, addiction, and withdrawal. While we seek to empower individuals to have control over their use, we are not “anti-weed” and we support efforts to legalize adult marijuana use and study.

    I recently decided to quit smoking weed after over 10 years of daily use. It has only been a month but every night I have vivid/disturbing dreams/nightmares. It has gotten to the point where I don’t want to go to sleep because I don’t know what I’m going to experience in my dreams/nightmares each night. I was hoping to find natural alternatives to assist in my sleeping or understanding how long they will last/when they will stop. The thought that it could last for months scares me, I may take up yoga or a work out routine to see if it helps because I do not want to take another drug for sleep assistance.

      Enjoy the visualisations they are just dreams … I think they are just our fears and worries that are presented to us in a surreal way that we stopped thinking about when we started to smoke weed in the first place … some of my dreams are beautiful and I see old relationships and people I’d let go of in the past … now I am older I see how naive I was at the time and actually miss the life with those people and think about how I left them and that life that I couldn’t handle for good and bad behind … live the rest of your life with embracement … the past has gone and now we move on to better experiences in a more mature way …

      You can try Melatonin. 30 minutes before your bedtime, take a tablet, or gummy, or strip of melatonin. Start with the lowest dose, i.e. 0.3 mg and slowly increase if it doesn’t help. You shouldn’t need more than 3 mg per night.
      Take it for around 7-10 days, until you feel you’re back to your regular circadian rhythm, and enjoy restful and sound sleep!

    • Stephen says:

      It’s been 9 days but the dreams are so vivid I don’t want to sleep anymore

      • Victoria says:

        I stopped smoking a month ago after around 8 years of daily use(abuse) dreams are super vivid I find a good way to let go of them is to keep a diary once i finish writing it i like to imagine it has left my head now, yoga+ gym are a great way to help with wothdrawl symptoms as well as prayer 🙏🏼 i hope this helps someone lets make this world a better place❤️

        • Victoria says:

          Also guys if you want to use something to help you sleep a glass of warm milk or just a cup of herbal tea to calm your system down is so much better then tablets like melatonin which have some bad side effects themselves we can get through this all you need is you

      Just embrace it and let it go through the whole course, you quit weed for a reason so don’t be so quick to replace it with something else because then are you really better off at all? Take a week or 2 off work so you don’t take frustration out on people you care about but at the end of the day just let your body do what it needs to, to get through it.. you will be better off in the long run, sooner you go through all of this, the sooner it will be over

  • Nixon says:

    I recently read an article saying cannabis doesn’t actually interrupt REM sleep but rather slow wave sleep. We just can’t remember and they’re closely linked

  • Not saying says:

    I’ve smoked weed multiple times a day (5-6 times per day) for over 15 years. I deal with high amounts of PTSD due to my job as a Firefighter/EMT and the dead bodies I see on a regular basis. I had to quit using weed to keep the bad thoughts away for 2 weeks because it’s against the rules for work etc. I treat it kind of like alcohol where I won’t get baked before work (don’t want to get someone killed) and do it responsibly at home on my own time (because it suppresses the traumatic ptsd moments I have regularly). It’s been 2 weeks since I quit and, Boy can I tell you, my dreams have turned into nothing but nightmares of kill or be killed scenarios, watching family members die horrific deaths, screaming in my sleep, night terrors, waking up in a pool of sweat (once I thought it was blood from dying in the dream). It’s weird because I pass out every time my head hits a pillow during the day but at night it’s really difficult to finally fall asleep. Just tonight I woke up 4 times now in 3 hours dreaming of my cat being invincible like wolverine and watching my brother get crushed by a trash truck and one about my kid being born looking like the alien from alien. I’m really freaked out and really want to use again just to make it all stop and to get real sleep. I’m considering seeing a shrink about it but I remember the last time I quit (for a job interview) and it didn’t help at all. They just keep trying to give me other medications that I wasn’t allowed to take because of regulations at my job. It sucks.

    • Sinead says:

      Hi , can I ask how long it took you to experience these dreams/nightmares as I’m on day 6 of no weed and haven’t had one bad dream still don’t remember my dreams when I wake up I was a heavy smoker 6 dons a day

  • Mr C says:

    That must be awful … and you have an heroic job it’s a shame these traumatic events come back in your dreams and thoughts whilst you sleep … just think though of all those people that benefit from your chosen profession … your help towards others has not been in vain how little or how great … your memories of the traumas is just a buy product / we are human and we see but don’t forget / your actions in your chosen profession and all of your work mates far outshine any past memory that may have been suppressed by smoking weed … I’m sure all the people that have passed or present thank you and your efforts … I’m sure they will wish you luck in life now …

  • Michael says:

    I’m 33 and been regularly smoking multiple times per day since I was 18. I recently stopped due to a change in diet and preference not to wake up hungry in the middle of the night. The only withdrawal symptoms I have are fluctuating body temperature, and SEVERE disturbing dreams at the end of my night of sleep. I have dreams that someone is sleeping with my wife while my house is being robbed while I’m searching for my gun panicking. I then wake up in my bed in a pool of sweat shaking realizing I’m STILL in a dream within a dream. THEN i finally wake myself up shaking, sweating, and confused. I would love for there to be a medication to prevent these dreams. Like a previous comment in this thread, I choose not to go back to sleep knowing I’ll access and continue the exact dreams….I’m a little over a week into my hiatus. The last time I did this, the dreams lasted one month before I decided I had to start smoking again simply to stop the dreams. Brutal….

    • Michael says:

      Update: It’s been about 3 weeks since I quit and 9 days since my blog post above. I feel more energy in the day, but the nightmares and intense dreams have yet to slow down. I find myself dreaming nearly all night. Sometimes one hour of sleep feels like I crammed a months worth of intense and sometimes recurring dreams into such a short time causing me to feel beyond exhausted all morning. Sometimes a quick hour powernap mid day helps and sometimes I still dream during a quick mid day nap. I’ve almost made it a month so I can’t cave just yet. Trying to ride this out until the dreams slow down but this could be a long process reprogramming my brain after 15 years of basically daily smoking…. If anyone has advice on medication to slow dreaming I’d love to hear. Occasionally I have more lucid dreams if i’m not having nightmares which is pretty cool.

  • Lanr says:

    Thank. You everybody for the comments,they let me know I am not alone, I stopped weed a month ago after 50 years of two joints a day, think of how many houses I could have bought. I started when I was an 18 yo Marine in Vietnam, I stopped a month ago after moving to Florida, because I don’t want hassle from cops over a joint, also for those 50 years,I got my weed from the same guy, I don’t trust other dealers, I moved out of or should I say forced out of San Francisco where I was born and stayed till. I was 60, The Marines thought me, you will adapt to your environment, or die. I moved to Scotland 5 years ago, in the mountains in a small cottage with no person around me for thirty miles, America got to crazy for me, my friend sent me the weed quarter pound every 4 months, I would smoke a joint in the morning before starting my 10 mile walk through the forest, the weed enhanced my observations, Scotland is extremely beautiful with unbelievable amount of wild life, it was a real dreamland., until covid exposed the Scottish govt to be A bunch of power ,control facist communist assholes, just like America, I had no choice but to escape, or be forced to take a vaccine wear a mask not be allowed outside etc. Florida looked like the only place, I made the trip via Iceland, Greenland, Canada by small private plane then buy ground to Florida, the nightmares from stopping the weed is incredible .but please. Never. Try. Ambien, never believe Doctors the pandemic or China attack, has proven them untrustworthy, now we are back to scarring young people with nonexistence nuclear weapons when you see America is Disneyland, unreal bullshit for money, I said I stopped weed it’s easier than quitting, so now at 68 my old friend will send me 2 pounds of weed to Florida. I ‘ll pack up my truck and head for the forest of Alaska, as A MARINE. I can’t give up the pursuit of Freedom eventhoug it’s an illusion, I’ll stick to my two joints rather than the effin nightmares,, thanks again to all, Sergeant Corns 2753213 USMC.

    I smoked on and off for 65 years. The last 3 years every night, in my apt. in the evening only. I am now one week off weed. Everynight I do have vivd dreams that seem to wake me always around 3:30 am. At that time I take 3 mg melatonin and fall back to sleep, and do not experince the vivid dreams. I am 83, the lack of quality of sleep really puts me on edge during the day. Sometime I take 1 mg of atavan which does help. But I am not going back to weed, because I believe after all the years of usage and the increase of thc I have become allergic to weed. Extereme itching, mainly in center of back. Also extreme nausea in morning. Since stopping for one week, itching is 50% better and nausea has gone completly. Hope this is helpfull.

    I hope this is helpful to someone!

  • mike says:

    I feel more in control of my life, without weed!

  • Andy H says:

    After quitting cannabis after many years, I too am in ‘The World of Dreams’ as I call it.
    A world in which anything can happen from anywhere and does, in full colour and audio.
    I compare it to the brain being like a computer that, due to cannabis, has been off-line for many months, or even years.
    Now, after quitting, it’s like going back on-line and finding that there are many, many updates ready to be instaled.
    Keep them coming. Sooner or later you’ll have the latest, and best, version of your brain.

    Smoked weed for 53 years stopped because visited another country sleep is still easy for me but dreams are remembered now. I don’t feel like I have any withdrawal symptons after 3 weeks without. Life goes on just a little more bored with it. Everything’s better with a bag of weed. : )

  • Dev says:

    I am 28 years old, a smoker of 12 years. I used recreationally multiple times a day (all day, basically) and also medically to help nausea. I stopped smoking the first week of July, as I was experiencing some medical issues and noticed it was really triggering my anxiety. The first couple weeks were ROUGH. I could fall asleep easily, but as many have stated above, did not want to ever do so because of the fear of my nightmares. I basically had nightmares for two straight weeks, intense insomnia where I could only sleep about 3-4 hours a night, and sweating/shaking symptoms. At about a month out, I can say that I am finally getting through the night and sleeping ~7 or 8 hrs a night, no sweating or shaking.. But I do occasionally still have nightmares, and I feel like I dream nonstop through the night. If its not a nightmare specifically, it’s a stress dream or a very obscure lucid dream with themes I don’t necessarily wish to think about (people I’d rather not see, places I don’t enjoy going, etc). During the day, I don’t even think about weed any more, which helps while I’m awake.. But night is still admittedly hard on me. I hope to see a lessening, soon.

    I have stopped to smoke after 22 years heavy smoking. Although I am very active like 10k running twice a week, playing football 1-2 times per week, going to gym the rest of the days leaving 1-2 day for rest. I have noticed that when I am stressed due to quitting job and try to settle in new job makes dreams more vivid, although I am not more tired than I was smokimg 6-8 joints per day. After 6 weeks of no smoke, I am more energetic, but the dreams are still vivid and sometime I woke up not knowing for few second if it was dream or not. Strange enough, had no sweating in the first 4 weeks, but now it is more common. I have noticed that if I sleep at open window, I am less likely to sweat. Also, drinking alcohol reduces the vicid dreams, but it is not sustainable to drink. Now I will try CBD oil to see if that helps. I dont feel too much stressed about it, some dreams are better and many times, I am laughing after the dreams, but it is so vivid.

  • Stephen says:

    My name Stephen.. I’m 23… I been smoking weed for 6 year and i decided to quit 9 days ago.. I had this vivid dream last night a guy I knew who hated for people to pass through his backyard as a shortcut.. this dude got in his car and chased me so vivid I woke up immediately.. I had this gang chase me and my friend to a restaurant so bad I grab a knife to fight people with guns lol woke up immediately.. I smoke weed because. I’m creative, that I start to scam people.. I had ideas that I really would ask myself wtf.. honestly. I just need someone to talk to and know I’m not alone..this is my email

  • Bruce says:

    I’m relieved to see I’m not alone in this. Exactly a week after I stopped, the dreaming started again. Not good dreams, disturbing lengthy ones like stories. Sometimes 2 in a row. Its 3 weeks now. Hopefully they taper off soon. It’s not fun.

  • Donna says:

    I have smoked a joint a night for 48 years. It’s now 21 days of not smoking. I have no appetite, I can’t sleep, my dreams are more like nightmares. Scary, angry dreams. I get night sweats.. I started smoking weed at 13. I an now 61. How long will this last? Is it that severe that I need to seek help? I don’t want too take any drugs to help in this situation. I would like to ride it out and quit forever. I am so tempted in lighting up a joint right now but I don’t want to give in. What can I do? How long will these symptoms last?

    • Anonymous says:

      Dealing with very similar symptoms and all I can say is stay strong. We’re all quitting for a reason and their is a light at the end of the tunnel…. Never thought my dreams/sleep would be the hard part… but it is…. I’m 2 weeks in and just going too hope that only a couple more weeks of this dreaming and I’ll be rewired. Also watching positive movies from my childhood helps, just putting it out there. God bless

    Quit smoking marijuana under a Cardiologist recommendation, as I have afib. I used to toke it periodically all day, 7 days a week. I too had vivid dreams, and some were really wierd. One was from a book I was reading about the French Revolution, and I had a dream where I was with a crowd of people watching executions on a guillotine. It was so realistic and amazing. I woke up and was like “what the hell”? Its nice to be able to remember dreams again, keep them coming as far as I’m concerned. Knowing that it was withdrawals from weed, it just gave me the incentive to continue quitting. :Used to laugh and tell my friends what will I dream about tonight. Other than an occasional craving I did fine. Our bodies are amazing, how we can heal ourselves. Some of us take longer than others we are all so different, but it is great to know that you are not alone in this and that, made me feel a LOT better.

    i have smoked for about 20 years on and off. for the last 2 years have had 1 spliff at night to help me sleep. stopped smoking completely 8 weeks ago and the nightmares began. very vivid. sometimes so scary that i cant/dont want to go back to sleep. im shouting in my sleep and waking my daughter up. getting to sleep ok but waking up an hour later and tossing and turning. constant headaches although they feel like muscular/tension – could be because im tense in my dreams. i thought the bad dreams would only last a week! nice to know im not the only one but wish it would stop. not missed the habit but so tempted to have a smoke to stop these nightmares!! good luck to anyone trying to quit because its definitely not easy

    Been smoking for 16 years(alot a day , everyday)and recently quit as well due to weed just giving me anxiety like it all switched one day and instead of it helping me it was making me feel worse…. Sometimes I would have to walk outside barefoot to just ground myself to the earth as weird as that sounds…. It would work every time…. But I’m about 10 days in and the dreams are unreal… scary , lucid, helpless , you name it, it’s happening ( the worst are the Erie feeling dreams like you know bad things are about to happen and you can’t get out of them , real Steven king stuff …. I’ll wake up around 530 am after going to bed around midnight and have to process my dream for a min before talking myself into going to bed again. All your stories really helped me tonight as I needed to hear that I’m not alone as well…. We are all
    Looking for somthing more from ourselves and I’m just proud of everyone of us doing what it takes to make the change…. I’ve been watching positive movies from my childhood some nights it helps a lot , also i try a couple shots of tequila witch does the trick , but we’re gona dream I now know from all your stories, it’s now part of our healing process….We Will Make It Happen We JUst Have To Stay Strong

    I was an all day smoker. From eyes open until close. I am experiencing the crazy dreams , some scary and some just super weird and vivid. I thought my sweats were from peri menopause, but I see NO. When I wake up I have to get myself together because I feel like I am still in a dream. I stopped smoking 7 weeks ago, and they are getting less but super extreme. Now I even try to wake myself up knowing that it is a dream I feel better seeing that others are going through this. I do not want to smoke ever again. This gives me reason to never do it again. I can do this!

  • Rich says:

    I smoked for 45 years, last 15 pretty much daily, since I was 17. About a year and a half ago quit for 5.5 months. Vivid dreams first hour and a half of sleep. Dreams lasted about 2.5 weeks. Started smoking weed again. One hitters every hour or so about 1/2 gram a day~. Quit again after syncope and afib events. Been off now for just about 60 days. Dreams are every night for first hour and half of sleep. About every other night i’ll dream a second time after waking up from the first dream. My dreams aren’t scary, just about all are centered around loss of control i.e. driving a vehicle moderate speed but can’t steer it or stop it, some are about lack of control of people i.e like a customer from a service postion perspective. None are really scary unless you would be a control freak like me haha. Very vivid and often include people I know from family or co workers at previous jobs (i’m retired 66 yrs old). As I noted above last time dream period lasted about 2.5 weeks, this time been going on much longer but after about a month they stopped for a couple weeks, then started up again (sigh…..). I take lots of heart issue meds, stomach acid meds, cholessterol and prostate meds. I really don’t like taking all the medicines but docs say I need to. Hope the dreams taper way off soon. I’ll try to report back. Thanks for everyone being here and contributing. Tonight I thought maybe I was losing it. Peace from Maryland!

    Good to see we aren’t alone and that helps, each person has different withdrawal symptoms and some have all that are possible.. I am 23 and have smoked at least 2 grams through a bong every single day since 15 years old.. i am going through crazy dreams and nightmares, sweats and frustration and can’t regulate body temperature but the thing that is helping me is just knowing that it will be so worth it in the long run. I have taken 3 weeks off work to help so I don’t take frustration out on anybody, I don’t know how long this will last as I quit about a week ago but the dreams are kind of exciting in a way, I haven’t dreamt like this since I was a kid (they were never quite like this tho)
    Literally as soon as you close your eyes, you are back in some wild dream, they feel so real when you are asleep but as soon as you wake up and come to, look back at your dreams, they are trying to tell you something and can be quite beautiful. I have met celebrities and seen family members and friends that I have lost over the years..
