So last night I think I came very close to an astral projection but I am still kind of confused on what I'm supposed to do.  So I was lying on my back, which is impossible for me to fall asleep in, listening to delta waves.  My body became numb as usual and started tingling and vibrating.  I kept drifting from "daydreaming" to realizing I was laying on my back.  After about an hour the vibrations abruptly stopped and my entire body felt numb.  I kind of felt myself lifting and I paniced which brought back the vibrations, the stage before I am assuming.  So my question to you guys is was I close?  What should I do once I pass the vibration stage?  I hope this made sense I appreciate the responses in advance.
