Some experiences are so eerie they stay with you forever. One person unearthed a box in their backyard filled with letters written by their future self. Each note revealed deeply personal truths, until the last one warned: “Don’t open the door.” At that very moment, a knock came. Against the warning, they opened it and saw a blurred-faced figure with familiar eyes—only for it to vanish when they slammed the door shut.

Another night, someone received a frantic call from their mother claiming she was locked out. But when they rushed home, their mom was still asleep in bed. The call had come from inside the house, and the voice on the line… wasn’t hers. The realization left them shaken, unsure of who—or what—was behind the call.

In a different story, a person discovered a disturbing photo on their phone of themselves sleeping, accompanied by the caption: “It’s watching you.” Checking their security camera only added to the terror, showing a shadowy figure at their door before the footage abruptly cut out. The unanswered question of who took the picture lingers like a nightmare.

Others shared real-life brushes with danger: one traveler in a bug-infested motel hid in the tub to sleep, only to be startled by a man crawling through the window. The intruder acted offended, cursing him for leaving the window unlocked as he retreated. Another recalled being 10 years old, approached by an elderly couple who persistently pressured him to get in their car under the guise of giving directions. Trusting his gut, he lied about where he lived and walked toward a random house until they left—likely avoiding a horrifying fate.
