Creepy describes something that makes you feel unsettled, nervous, or afraid in a subtle, hard-to-explain way. A creepy feeling isn't like being suddenly startled by a loud noise. Instead, it's that uncomfortable sensation when something seems wrong or off, even if you can't say exactly why.

An abandoned house with broken windows might feel creepy. A stranger who stands too close and stares without smiling acts creepy. That eerie feeling you get when you're alone in a dark basement, or when you notice someone has been watching you without you realizing it: that's creepiness.

The word often describes things that seem almost normal but have something disturbing about them. A doll with a strange smile might be creepy. A too-quiet forest where no birds are singing can feel creepy. Stories often use creepy details to build suspense: flickering lights, mysterious footsteps, or doors that slowly open by themselves.

Sometimes people use creepy more casually to describe anything that makes them uncomfortable, like eating food with an unusual texture or seeing an insect with too many legs. But the word works best for that specific chill you feel when your instincts warn you that something isn't quite right.
