High Times dives deep into the science behind marijuana and dreams.

I don’t know about all of you but, when I have trouble sleeping I turn to a nice, full flavored indica to help knock me out. It’s super effective; I typically wake up feeling rested and ready for the day, but something peculiar has been happening, something that was missing, something I didn’t realize until a friend asked me a simple question, “What was your dream last night?”

I was racked my brain trying to remember but then thought, I don’t recall my dreams from any of the times I toked before bed. After talking with some friends, and going through the /r/trees subreddit, I found that other reefer-sleepers had the same phenomenon—no stony marijuana dreams.
