I'm pretty sure I saw both of them on FearNet, somewhere around 2 or 3 years ago. Here are my vague descriptions, hopefully they will trigger a name in someone's brain.
So the first one, it's mostly set in a really dirty apartment building in New York (I think). The guy ends up hallucinating, there's a guy who lives in the room upstairs who doesn't really exist or maybe he does. It was made between 1997 and 2007 probably. Uh... I think it had a one word title. Real helpful right? Unfortunately this is all I can remember. It was so good though.
The other one is like, this woman just gets released from a mental hospital for being schizophrenic so she stupidly goes to a farm house in a small town to "calm down and get back on her feet". But of course, the house is haunted when they get there and it turns out the whole town is ghosts who want to kill her. But, she sees the signs before anyone else who's with her does (maybe just her husband), so she doesn't want to say it right away? It was like, the idea of being crazy and hallucinating, and then actually seeing crazy shit, like, oh no! I'm actually not hallucinating at all! Scary idea. This was definitely made between... 1977 and 1984.
