Clairvoyance is often seen as a mistake or a fake disease, and more often than not people who possess this capability are perceived as freaks of nature.

Princess Luna actually relies on this ability when she finds a crestfallen creature known as a Human drifting through the Dream Realm, and has asked for his clairvoyant power to help her foresee the future.

The Human is only visited by the Princess, and is destined to spend the rest of his existence watching his home on Earth crumble and decay, his identity stuck in a timeless empty plain of existence, stuck alone inside of his head.

This story is more or less based off of the song Clairvoyant Disease by Avenged Sevenfold, and a loose dream that I once had.
