How do people who've had otherworldly experiences conclude that the experience was real, and not, say, a hallucination or a dream?

Here's an example of the kind of problem with such claims. You state, as a bald fact, that " ... a medical doctor was told during a near-death event, that her young son would die before a certain age. A car killed him the day before that birthday." Well, we can't prove or disprove the communication, but we should be able to document a lot of the elements of a story like this one. For example: What are the names of these people? When and where did the near-death event and the son's death happen? Where can we find a first-hand account of the story, told or written by the mother? Are there medical records we can read from her near-death event? Any news stories about the fatal car accident? Can we examine the son's birth and death records? Etc. If we can't verify these mundane facts, why should we give any credence to the claim that she was given information during a near-death encounter?
