Jus got done with it and i'm thinking its all in one world then at the, when the airplane is caught in the tornado, the engine is thrown back in time...into another dimension

All dimensions are exactly the same to this moment....in the dimension this movie is set, where Frank has warned hime, his world(this dimension) has ended cuz his his girl's gone, he's alone, and he's killed someone...Donnie isnt dead at the end but his life will be over




man...this is my take, but i need to watch it again 1st time
great movie
