[Ive had one instance where I heard , at the top of my head , electrical current sounds. Only experienced this once, but found it to prove the theory that our etheric bodys do exit from the top of the head. Other obes Ive had , Ive felt a black out when my body ends its departure, my head last.
I constantly get these super-loud cracking sounds, similar to a gunshot, accompanied by a jolt that goes from head to toe. I believe it's fairly common. But my etheric body dosen't leave through my head - at least not when I've been aware.
