If I am exhusted from not being able to sleep. Right when I am drifting off, I will start to talk to others but not with my mouth. It is like regular conversation but its my mind and I hear a voice in my head almost identical to someone sitting next to me talking in my ear. Call me crazy but it is like esp with a spirit or something. I can think conversations back and forth with my wife when she is sleeping. But this is not something I can control, it just happens or it does not happen. Any one else have have this happen?
