I think I've been hearing these so-called astral noises for as long as I can remember. I would be lying in bed on the verge of falling asleep and someone will talk or scream or laugh. The other morning while in a trance I heard an old-timey phone ring ( like a rotary phone). All this time I thought it was my brain's neurons firing at random in some long forgotten sound memory area. If I think of it this way instead of someone trying to scare me out of projecting, its not nearly as scary to me.
Yep, sounds like astral noise to me. You can actually focus on the noise to deepen the trance. During my first OBE a sinister-evil laugh scared me out of a projection. I wish I could go back and face it now. :lol:
