Right now I'm trying to Astral Project/OBE. I know that I have to be conciously awake, but the body sleeping. I try to concentrate on something so that I won't completely fall asleep and dream, but I obviously fail since I wake up the next morning not remembering what really happened last night. Can anybody give me tips?

BTW I have already experienced this "surge of energy" that you're supposed to feel. Amazingly I felt this surge on my first try, but I just couldn't separate as I was still awake and I just got frustrated that I couldn't separate so I stopped and went to bed normally.

Are there signs that will show if I'm sleeping, but still awake and aware of my surroundings or that I can have an OBE? Thanks in advance. This has been troubling me for a while now.
