I think you are referring to “Account of an Interesting Out-of-Body Experience.”
I refer to a video by the person who experienced it, Eben Alexander.
– He has also written a book “Proof of Heaven: A Neurosurgeon’s Journey into the Afterlife” about that experience.
Such experiences can vary a lot. Furthermore, it is likely that only “good experiences” are publicized.
– There is one common “good aspect” associated with a gandhabba. It is the fact that there is no “solid body” associated. One feels the “lightness” and move around at great speed.
– Another is that in all those accounts they “come back” to human life within a relatively short time. The frustrations that arise due to the lack of a “solid body” come when one realizes that one is unable to eat, smell, or have sex.
