Why do some people enjoy scary movies and rollercoasters?

Some people enjoy scary movies and rollercoasters because they feel excited by unexpected surprises.

Scary movies are like when you're playing hide-and-seek and suddenly someone jumps out from behind the couch. You might scream, but then you laugh because it was fun. In a movie, the characters get scared of things that aren't real, like ghosts or monsters, and that makes you feel a little bit scared too, but also happy.

Rollercoasters are like when you're on a really bumpy ride in a car. You go up high and then zoom down fast, making your tummy feel funny. Rollercoasters do this in a controlled way so you know it's safe, even though it feels wild!

When something surprising happens, like a jump scare or a big drop, your body gets ready for action. Your heart beats faster and you feel more alive, just like when you're playing your favorite game.

Some people love this feeling of being surprised and excited, even if it makes them a little nervous!
