I don't know how you can watch these things.
I'd struggle to watch them in the middle of the day.
They're screamers, though. Low-tech scares that, if you're me, are the bad kind of scary. Sitting there shaking in your chair breathing heavily, type. The *good* scares are the unnerving ones, where the feeling sticks, for a few days even. Just a feeling that something wrong is afoot, the type you might get from Marble Hornets, or creepypasta
