How Does Neil deGrasse Tyson explains why some people see ghosts Work?

Imagine you're playing hide and seek, and you think someone is behind the couch, but when you peek, there's no one there. That’s kind of like what happens when some people see ghosts.

Neil deGrasse Tyson, a super smart scientist, says that sometimes our brains trick us into thinking we see something that isn’t really there. It's like when you're tired and your eyes feel funny, you might think you saw a shadow or a flicker of movement, but it was just your brain playing a little game.

Sometimes people are in places where they’re used to being alone, like an empty house at night. When the lights flicker or there's a sudden sound, their brains go "Hmm… is that someone else?" Just like when you're watching TV and suddenly think you see a face in the screen, it’s just your brain making up a story.

When people believe they saw a ghost, it can feel super real. But it's kind of like dreaming, what feels real while it's happening might not be real when you wake up or look back at it. So, some people see ghosts because their brains are just having fun and making up stories!
