They linger in your mind long after the credits roll, making you question the shadows in your room and the noises in the night. So, if you’re a seasoned horror aficionado or a curious newcomer looking for a good scare, here’s a list of the top 10 horror movies guaranteed to keep you up at night, along with a little insight into why they work so well.

1. The Exorcist (1973) – Demonic Possession at Its Finest

Often hailed as one of the scariest films ever made, The Exorcist still holds up remarkably well.
