Do you believe in ghosts? We don’t. Not on the record, anyway. But sometimes, when it’s very dark, and when it’s very late, and the overall circumstances are very, very creepy—well, let’s just say we’re more open-minded.

We made these deeply unsettling GIFs from videos of what are touted as real-life ghost sightings. Some, no doubt, are hoaxes. Others are optical illusions.

The rest? It’s up to you to decide.
