It happened to me on my first trip but i took 900 mgs. in the form of Delsym. The Infamous DXM Tweek (my first tweek was from 10 P.M. to 2 A.M.), it happens when your alone, or you close your eyes for too long on the fourth plateau. Everything from that night will eventually come back, and it isn't pretty. Let me guess you woke up with a more passionate love for close friends and family, right or wrong? In short terms you had a Near-Death experience and went out-of-body, you will probably remember repeating your dreams (visions when you close your eyes) and actions for a while. Another distinct feeling just before the tweek, is the feeling like your body was literally dieing. It sucks and makes you realize what the people around you mean to you. Next trip wait untill your sober to decide to sleep, believe me the fourth plateau is very long and longer if you up your dose. Beware you can fuck yourself up with this chemical over time, and quickly if you abuse it. Peace
