Out-of Body experinces.
I myself have had very little out-of-body experiences’. That I remember! My husband however leaves his body all the time. Mostly every night, except when he “asks” to stay in. He told his guides years ago to use him as needed “I’m here to help.” I feel that he often has other souls try out his body. Only for a few seconds or minutes. Mind you! I remember this one instance when he was in bed sleeping. All of a sudden he just sat up and looked slowly around the room. He moved so methodically and his eyes looked very unfamiliar to me.
By the time I got this is really creepy feeling, it was over! He just laid back down.
