is there anyone who completely understood the end of the movie ?

Rating: 8/10 (4 October 2006)

I liked the movie very much but i could not get the end of it.What happened to Donnie?He was on a hill standing and watching the clouds coming together as the darkness was falling.Then he went to bed with a big smile on his face and died at that night.But in the beginning of the movie he has already survived from that crash. Moreover, why did the girl Gretchen not recognize Donnie at the end? Anyway, Donnie's life is a bit complicated for me.He has a good understanding of physics which leads him to read the book given by his teacher.He also searches the answers for dying alone.I guess this is related with the reason of his death at the end. Shortly, i did not understand the time line of the film though i enjoyed very much.
