What are some really spooky one sentence scary stories?

One scary spooky story is 'The Tell - Tale Heart' by Edgar Allan Poe. It's about a man who is driven mad by an old man's 'evil eye'. He decides to kill the old man and hides his body under the floorboards. But he starts to hear the heart still beating, which drives him to confess his crime. Another is the legend of Bloody Mary. They say if you go into a dark bathroom, light some candles, and say 'Bloody Mary' three times, a ghostly figure will appear. It's super spooky.

I found a diary in the attic. The last entry said 'They're coming for me tonight'. And then there were scratch marks on the page.

The mirror showed a figure behind me, but when I spun around, nothing was there.

The haunted locations within the Queen Mary are very spooky. The pool with its tale of the drowned girl is one example. People have reported a distinct change in the atmosphere around the pool, a feeling of heaviness and sadness. And then there are the stories of the hallways where people feel like they're being followed by something they can't see. All these elements combine to make Queen Mary scary stories truly spine - chilling.

Well, there's a story about an abandoned asylum. In this place, patients were once treated very cruelly. Now, those who dare to enter at night report seeing shadowy figures of former patients roaming the halls. And then there's the story of the 'Cursed Necklace'. Whoever wears it is said to be haunted by bad luck and strange apparitions. 'The Phantom Train' is also quite scary. It's said to appear out of nowhere on old railway tracks and if you see it, you'll be cursed.

One scary Halloween party story is about a haunted mansion party. Guests started seeing shadowy figures moving in the corners. The lights would flicker whenever they tried to approach a certain room. Turns out, it was an old house with a tragic past and the spirits were not happy about the party.

Here's one. I woke up in the middle of the night and saw a shadowy figure at the foot of my bed. When I blinked, it was gone but I could still feel its presence.

The last person on Earth sat alone in a room. There was a knock on the door.

One scary story could be about a haunted doll. There was this old, porcelain doll in an abandoned house. At night, it would move on its own and make a creepy giggling sound. People who dared to enter the house often reported seeing its eyes following them.

Well, there's a story about a haunted mansion in Roblox. As you enter the game set in this old, decrepit mansion, things start getting weird. Doors open and close on their own, cold drafts seem to blow through even though it's just a virtual world. You might see ghostly apparitions floating around, and sometimes you can hear faint whispers that seem to be saying things you can't quite make out. It really makes your heart race as you explore the place, not knowing what might jump out at you next.
