Maybe it’s obvious to some, but I think it is worth mentioning that people who experienced NDE are not clinically dead when they saw themselves hovering above their physical bodies. There are buddhists who do not accept the concept of a Gandhabba, claiming that once a person dies, the next arising consciousness will effect a rebirth elsewhere. Let’s not forget, to be reborn as say, a preta, one’s life vitality has to cease first. So, what is this thing that is capable of revealing vivid details after the person has woken up from comatose? I think the implicit evidence is enough to deduce that it must be a Gandhabba rather than a preta.
