An spooky place or situation is often eerie and frightening, but not necessarily scary.
Imagine watching a horror movie that's so intense it makes you feel like someone's following you home. Or walking through an abandoned house at night when every creak of the floorboards sounds like a ghostly warning. That's what people mean by "spooky." Sometimes it's just a fun way to describe something creepy, but other times it can be genuinely frightening. It's often used in conversation about places or situations that feel mysterious and unsettling, but not necessarily dangerous.
Eerie, or suggestive of ghosts or the supernatural.
