One true untold scary story is about a deserted house on the outskirts of a small town. People say that at night, you can see a faint light in the attic window. A group of teenagers once decided to explore it. As they entered, they heard strange creaking noises. Suddenly, one of them felt a cold hand on their shoulder, but when they turned around, there was no one there. They ran out in fear and never went back.
One that sends shivers down the spine is the story of a ship at sea. The crew started experiencing strange phenomena. Tools would move on their own, and they heard whispers that no one could understand. Then, one by one, the crew members started to disappear. The last survivor found a diary in the captain's quarters that detailed some sort of curse the ship was under, but before he could do anything, he too vanished.
Well, it's a mix. Some of the untold stories could be true representations of what happens in an ER, but others might be exaggerated or fictionalized to capture the audience's attention. Without concrete evidence, it's difficult to determine the complete truth of such stories.
