Many years ago in a Florida gym I was talking to an older guy and he grudgingly told me an identical story. He was in a Volkswagon bug and had a bad accident, he remembers leaving his body, floating up and hovering over the scene watching and listening to the events happening below, at some point he zipped back into his body and regained conciousness. I had to pull this story out of this guy as he was reluctant to tell it for some reason. I still haven't heard a good explanation for so many thousands of people relating the same events, it's simply illogical for them to all tell the same story.
In short, I have seen myself out of body,
I am not interested to write a long as story about myself in a public forum.
But if you are interested in such things..(its maybe not 100% the same but you can see yourself from the outside)
salvinorin A can trigger out of body experience. (there is no guarantee of course)
DMT which feel like dying as they say. (no personal experience.)
You can also have a out of body experience in a sleep paralysis.
You can trigger sleep paralysis with Huperzine-A (high probability)
Or with Entada rheedii (no personal experience.)
And you can also learn it the nature way.
You see yourself from the outside 100% how you look with all the Details.
(Not all people see themselves, but they see other things)
The easiest way to do it is: (it works best if you are realy tired)
Lay straight on your Bed. (in a comfortable position you have to lay without moving)
Don’t move for 10-30 Minutes (try realy hard to get your heartrate down)
Try to be awake the whole Time
Don’t move for the tiniest bit. (maybe you have to practice that)
That’s it.
