Carl Sagan had a simple test for “out of body” experiences. have a nuetral person place a book on a high shelf open to a certain page. Then the “out of body” person simply goes there and looks, and when they return they can tell what the book and page was.
I think there was like a $10,000 prize or reward for a successful test inder controlled conditions, but according to the “believers” it can’t be done if skeptics are presant because the “vibe” is wrong or whatever.
So far, no one has successfully completed this simple test.
