I just discovered this interesting anime on Tubi called Kowabon. It's a series of horror stories involving supernatural forces and technology. Each episode is 3 minutes long, and that makes them really punchy.
Strangely, it seems like it was actually filmed with real people and somehow converted into an anime, since we always see shots of the actors and the crew at the end of every episode.
I think the episodes are fascinating to watch and really creepy. If the idea of seeing ghosts through a camera gives you shivers, then you'll love this anime.
