Sleeping in Trance

[whatsername100]

I just had a semi-trance. I went under during the induction, but I think I fell asleep, because I didn't remember the file's contents, and I woke up the next morning. I've been in a real trance before, and woke up at the awakener, but that was a while ago. The good news is that I went under at all, but the thing is, last time, I tried letting my mind wander, and I got the sleep-trance. Now when I try to get into trance, that's all I can think about. I can't let my mind wander unintentionally. What should I do to acheive trance again?
