On the prebiotics, you do get CRAZY vivid dreams, and you can lapse into the dream state quickly (within minutes; I know this from looking at the clock, falling asleep, and then waking to my alarm). Until you do the stuff, you have no idea how dynamic and off the wall your dreams can be. And oddly, you can remember them. I hate people who tell others their dreams, but here's one example from a couple nights ago: Winona Ryder and I had gone to high school together (in my dream, not real life), and now she was my girlfriend. I could not tell you where the heck any of that came from.
