Monkey Thoughts

Very creepy and beautifully shot flick. A woman moves with her husband and son back to the orphanage she grew up in to renovate it and open it as a home for disabled children. But slowly, her son starts acting odd and talking about invisible friends. And that's just setting the mood!
I find any movie that involves creepy kids to be especially scary, but this one really did it well. Watch it with the lights out!
