I watched an interesting movie last night. Psychological thriller/horror called The Evil Within.
It's about a mental disabled young man who lives with his older brother. A mirror he hates starts talking to him, and making him do things...
Some sections are partially dream sequences, while representing things which really happen
... if that makes sense
Here's the opening scene:
And the full movie is available to watch on youtube too:
