I'm far from a seasoned astral projector. I rarely leave my body for even a few seconds. Usually I feel the vibrations, here some buzzing or beeping sounds and only manage a partial separation. When this happens, I'm in my bedroom but it's quite dark. If this happens at night when it's pitch black, it also happens to be nearly pitch black in my OBE also except for the outline of a few objects. This can be slightly scary, and my experience doesn't correspond to experiences that others write about in their astral projections.
