Ya, Ive heard cannabis affects REM sleep before. Seems like I hardly ever remember my dreams when I smoke, but I also get on a great & consistent sleeping schedule on weed so shortened rem might make the most sense. These crazy dreams have been mostly fun. I had one super weird sexual dream that was too weird to share with anyone, was the closest thing to a nightmare so far but wasn’t scary at the time, but when I woke up it was scary 😂
