Aha , i can also remember same kinda movie , related to deja vu thing ( to know before it happens ) ,
IFonly , for first 30 mins it was something , i couldnt understand what all was happening , but later on how the movie catch up was amazing .
Its a kinda story , a guy saw the death of his GF in his dream , and later on he realizes , the same things were happening to him , but yet he have a chance to change the things and save his gf .
Amazin movie ... he manages to do but it cost him his life .
