Need video clips with scenes from insane asylums.

So, I have a video Idea, however, I need miscellaneous clips relating to insane asylums and prisons, showing hallways, maybe with screaming or yelling, someone in solitary confinement, that sort of thing. If they are from movies that is alright but I don’t want it to be super obvious it’s a movie scene.

Also, if there was a clip, not showing it happening directly, but someone being put in an electric chair, and then not showing the death but possibly the guy throwing the switch and lights flickering or something like that.
