…friend, twist ending).

I’ll try to explain this as clearly as I can, but I watch so many horror movies that I’m afraid I might be mixing two together at this point.

Notes:

• Color, saw on Netflix about two years ago, 2000-present, very dark/low-light feel, possibly indie movie.
• Set entirely inside an apartment building. I remember there being old glass pane doors at the front, and stairs that led upstairs. Unsure if the upstairs was occupied – we never see them (I think). The downstairs (on left) apartment is where this takes place.
• Young couple (all British cast, I believe) in their home. Something seems to be uneasy about the place (lots of shadowy movements, noises, etc), and it is escalated when their friend (male, friend of the boyfriend) comes to stay.
• The friend explains that he has either just broken up with his girlfriend or they’ve had a huge fight and she’s refusing to return his calls. He’s super upset and asks to stay with the couple for a few days. He seems pretty mentally unstable
• From this point on, I’m not sure where the demons/possession is coming from … but it seems to take over the house/apartment. I think they become more concerned for the friend (maybe he’s getting sicker? more distraught? maybe the haunting is related to his emotions? I can’t seem to remember) and for some reason, they just don’t leave the damn house.
• At one point I remember them all running upstairs to “Get away” from these things, where they stumble across some kind of old newspaper clippings/evidence that leads them to believe the place is haunted/possessed. I’m not sure what this has to do with their crazy friend

****** SPOILER ******* it turns out, in the end that the friend actually KILLED his girlfriend because of these crazy demon things. I remember the wife/gf of the orig couple winds up murdering the friend in the end.

I HOPE that someone knows this – it’s been driving me crazy! It was a really well done movie. Really great close shots and very moody. Whoever the director was did a great job and making you feel trapped and paranoid. Lots of “bumps in the night.” Not gory, very creepy.
