I'm having a really difficult time finding out the name of this movie?

ok, so a couple years back maybe like 3? i watched this movie that involved a young man, maybe 18. some how he ended up at the side of the river but he was unconsciouss and somehow his soul was able to move around, even though his body was laying there. then his soul went back to his family and friends and he yelled and did everything but they just couldnt hear him or see him. and then later it turns out, as a soul, a yellow bird that didnt quite die..it just fell unconscious. and the birds soul was moving around just like him. then he saw a cat eat the body of the bird and then the soul of the bird vanished. then he realized that thats whats happening to him. yeah so i cant figure this one out. id be reallllllyyyy glad if you could help out thanks!!
