Favorite Reality Manipulation Films

I did a re-watch of the film Resolution recently and really enjoyed it. I was giving it a mulling over and realized that I love films where this sometimes sad little reality of ours is turned on its ear and shaken a bit. The day to day horrors replaced by severe changes that no one expected. While I wouldn't want this to happen to me, I love the idea that there might be something more - something drastically different in the world.

Ghosts, paranormal happenings, UFOs....they all get me happy.

So, for this round of lists, I'm going with my favorite reality manipulation films. Films where things start off one way and get...strange.

(All synopsis texts are from IMDB)

Blood Punch - I love where this went
A young man is lured into a dangerous love triangle that begins to take a series of shocking and grisly supernatural turns.



Cabin in the Woods - Some fantastic writing and a fun idea
Five friends go for a break at a remote cabin, where they get more than they bargained for, discovering the truth behind the cabin in the woods.



Resolution - Pairs nicely with CABIN IN THE WOODS. Something strange is going on
A man imprisons his estranged junkie friend in an isolated cabin in the boonies San Diego to force him through a week of sobriety, but the events of that week are being mysteriously manipulated.



Berberian Sound Studio - A very Alice in Wonderland journey into madness
A sound engineer's work for an Italian horror studio becomes a terrifying case of life imitating art.


Coherence - Dude...just...whoa...
Strange things begin to happen when a group of friends gather for a dinner party on an evening when a comet is passing overhead.



Timecrimes - A fun offering from overseas. A great story
A man accidentally gets into a time machine and travels back in time nearly an hour. Finding himself will be the first of a series of disasters of unforeseeable consequences.



John Dies at the End - A really fun and imaginative ride!
A new street drug that sends its users across time and dimensions has one drawback: some people return no longer human. Can two college drop-outs save humanity from this silent, otherworldly invasion?



Time Lapse - Stick with it. It's a slow burn, but was worth the trip
Three friends discover a mysterious machine that takes pictures twenty-four hours into the future, and conspire to use it for personal gain, until disturbing and dangerous images begin to develop.



Identity - Just yes. 
Stranded at a desolate Nevada motel during a nasty rain-storm, ten strangers become acquainted with each other when they realize that they're being killed off one by one.




Plus One - Doppelgänger goodness
Three college friends hit the biggest party of the year, where a mysterious phenomenon disrupts the night, quickly descending into a chaos that challenges their friendships - and whether they can stay alive.

Amazing WTF-ness!!!   I loved this one! 

Have others that should be on this list? Let me know! I'd love to see them. Maybe I missed one I've seen before.
