It's like when a teacher gives you a homework assignment and you play with words on your paper to make it look long but it has 0 content in it, because you never did any research and wrote just the most basic ideas ever.
The acting was bleh, soundtrack was pretty nice and did create a tiny bit of atmosphere (because the characters couldn't). I'd suggest not to watch it (I did watch all of it), also it has a very open ending.
If you are into psychology, lucid dreams, dreams or sleep paralysis, you won't learn anything most likely, except that this movie will show you how much you actually know on those subjects and you will feel superior. Also watching this movie I thought it will get in depth and all I left was with wanting more, because it never got deep, just gave off some illusion of hope.
P.S
Also this movie is very predictable and doesn't even hide it, just to end it with "oh so who did it?" and it's never answered. And rossalex231, I believed in your review, you're a scam.
