I will say for everyone reading your description you do not sound like a whack job. On the contrary you do sound like someone that is quite reflective and perceptive about your experience. You do not sound alarmist nor hysterical. I think you had this experience, what it was I do not know, but you sound congruent to me.
BTW stay away from OOBE. You are not protected spiritually doing it.
Well said.
Especially the last part.
Evidently.
