I get really intense CEV's and if I binge and do it two nights in a row the second night I'm always tweaked out and hallucinate. I've since learned and now space everything out.
I've seen humans (not just outlines...full color humans) sitting on my couch talking to me and the last time it happened I was in bed and there was a long line of people just walking out of my bathroom, stopping at my bed to look at me, and then just walking past for the next person to walk up. It's freaked me out before but I tend to just go along with it as I know it'll eventually pass.
