Horror series with a runtime under 10 minutes

The best horror anime (in my opinion) that I've seen thus far. AKA horror anime I rated 6/10 or higher. Some are not labelled as horror on MAL. Some are not really that spooky either.
Organized roughly by my rankings.

I also like Sankarea and Gakkou no Kaidan/Ghost Stories (dub) but I don't think those are horror, so I didn't include them.

Also Memories is just referring to Magnetic Rose short film and Neo Tokyo is just referring to The Running Man and The Order to Stop Construction.


Not on MAL (yet):

Saka Men (6/10)
