Horror anime stories that doesn't make any sense at all

[Star_Of_Hope]

I have seen couple of horror movies and they don't make much sense at the end.
Like IT, Grudge and such. I have been thinking. Do we have such stories even in anime? I remember Yamishibai and it fits the bill

Basically.. every horror story didn't make sense at all
