For those who love Harry Potter, here are two of the fan theories circulating on the internet which are mindblowing and seem shockingly plausible.

1. DUMBLEDORE IS DEATH.
In "The Tale of the Three Brothers"—from The Tales of Beedle the Bard, sort of the wizarding world's version of Mother Goose—three unnamed siblings come face to face with the personification of Death, who offers them their choice of gifts. The first brother, convinced of his own superiority, chooses the Elder Wand, the most powerful wand in existence; the second brother requests the ability to resurrect loved ones from the dead, made possible by the Resurrection Stone; the third brother, humbly, asks only for Death not to pursue him, and is given the Cloak of Invisibility under which to hide. The three artifacts thus comprised the Deathly Hallows: real magical objects possessed by the Peverell brothers, and sought after for centuries after their deaths.
As if the lines between fact and fiction were not already blurred enough, some readers have astutely noticed parallels between the original brothers and another set of three “brothers”: Harry, Snape, and Voldemort. By their reckoning, Voldemort represents the first brother, lusting for power and seeking possession of the Elder Wand at all costs; Snape is the second brother, driven only by the desire to recapture his lost love; Harry is the third brother, ready to face Death and thus accepted as “an old friend.”
Moreover, this interpretation posits that there’s a fourth character from whom all the Hallows originate: Death, otherwise known as Dumbledore. The Headmaster is the only one, prior to Harry, to possess each of the Hallows: he presents Harry first with the Cloak, then with the Stone, and is stripped of the Elder Wand by Draco Malfoy, who then loses it in a duel to Harry. He is, however indirectly, responsible for the deaths of both Snape and Voldemort, and when Harry “dies,” who is there to greet him? Dumbledore, welcoming him like an old friend.
2. HARRY IS IMMORTAL.
This theory can be attributed to a level of close reading that would make any college English professor proud. Sybil Trelawney’s prophecy regarding the relationship between Harry and Voldemort, stored deep in the Department of Mysteries due to its potentially world-changing impact, is very particularly worded, with the relevant portion declaring that “either must die at the hand of the other, for neither can live while the other survives.” The obvious interpretation, and the one borne out by the ending of the series, is that Harry is destined to kill or be killed by Voldemort; there is no other way.
There is, however, another way to interpret the prophecy, which Imgur user HPWombat identified: If either Harry or Voldemort must die at the hand of the other, it is conceivable that the one to survive remains immune to death through any other means. Harry vanquished Voldemort, thereby satisfying the condition of the prophecy that indicated he could—but it may be that Harry himself is now effectively immortal. Those familiar with the Greek myth of Tithonus and Eos will immediately recognize the tragedy of such a fate, but there’s an additional twist for Harry: By sacrificing his death, he will never have the opportunity to see his family, even in death. That’s the darkest possible ending by far.
