Near-Death Clairvoyance

A character who is dead or having a Near-Death Experience steps out of his body and observes what is happening with other characters in the story at that time. The events so observed are shown one way or another to be real and not the fantasy of a dying brain. Alternately, the character gets to review key events in his life, providing the justification for a Clip Show. Either variant can turn into yet another version of Yet Another Christmas Carol or Wonderful Life.

The sequence usually ends with dead characters moving on to the Afterlife, and comatose ones waking up (occasionally as a Mistimed Revival). Reawakened and revived characters rarely remember the experience as more than a blurry dream, although specific recollections are sometimes allowed for punchlines or An Aesop.

Tabletop Games

 * Sin-Eaters who bear one of the Elemental Keys and the Oracle Manifestation get a fun variant of this -- they're able to undergo an out-of-body experience and travel wherever they wish. Thing is, to do so, they must take damage in one form or another. Depending on the Key in question, this may involve being buried alive, setting yourself on fire, getting strangled, or drowning yourself in the bathtub. Mind you, if you successfully pull it off, you're healed of all damage once you "snap back."
 * Similarly, Orpheus split the "Laments" between actual ghosts and living people who were able to project their soul out of their body. Skimmers could do it through meditation, but Sleepers required cryogenic tanks to bring their body to a state of "death" that would allow them to "vacate the premises." In fact, that's how Orpheus got into the "post-life management" business -- they were doing extensive research into cryogenics, and discovered an interesting side effect...

Western Animation

 * In Family Guy, Peter is struck by lightning and has a Near-Death Experience. He proceeds to steal money from his own wallet and later tries to reenter his body through the mouth, having about as much success as a flesh-and-blood fat man would have trying to climb inside an unconscious person. Death (a recurring character) shows up to hang out with him for a while as part of his Near-Death Experience, and when Peter asks when he's really going to die, he's told it'll be a few years after Lois divorces him. Peter tries convincing Death that'll never happen, and leads him through a bunch of flashbacks depicting their courtship, showing how deeply in love they were. In the process, Peter realizes that he's been taking Lois for granted lately, and has the epiphany necessary to save his marriage.
