I read that weed makes you not dream, then when you go off weed you have crazy dreams. So heavy, heavy weed users that quit, how long did you have crazy dreams for?
Weeks? Months? Years? Any other interesting experiences?
Not a weed smoker, but I am in mental health. Two things:
1.) That little factoid is a falsehood. Plenty of marijuana users remember their dreams.
2.) As indicated at the end of #1, you always dream when you sleep. You just don’t necessarily remember your dreams when you wake up. We don’t know exactly why we dream—there are several theories—but we know it’s an integral part of our sleep. It’s theorized that what we experience as dreams may be our brains encoding our memories of our experiences since the last time we slept into long-term memory and possibly doing a particular type of problem-solving about things weighing heavily on our minds of late.
I mean, they've actually done studies where they tracked people's rapid eye moments, and THC reduces the average person's REM cycles. Those cycles usually increase beyond the average person's when heavy users take break. Sure it isn't everyone, but it's the average experience with cannabis. There are a lot of aspects of THC that effect people differently, so you should be mindful of that when trying to speak with authority about it.
No, I’m afraid you don’t know how scientific claims work. The OP read a claim that “weed makes you not dream.” They didn’t read a claim that “some people report not dreaming after they’ve gone to sleep after smoking weed,” it was a blanket statement about an effect of marijuana.
The fact that you have gone to sleep after smoking and not remembered your dreams afterward does not mean it was the weed that did it, and it certainly doesn’t mean it has that affect on most people, let alone everybody. The issue isn’t that the OP’s claim is true because it happened to you; this is why anecdotal evidence is not accepted as a basis for factual claims in science. There are too many potential confounding factors in any individual case. Plenty of people claim to have seen ghosts; that doesn’t mean ghosts exist.
