ok, first of all, that movie could have been SO GOOD, unfortunately it was a piece of u know what. he really was in the car accident, yadda yadda, and everything was real up until that night he went dancing w/his friend and the girl, then after making a fool of himself, yadda yadda, he basically became an introvert, stayed inside all the time, and on the internet found out about a place that could freeze him after he died, and live in a perpetual "dream state", so he signed up for that and then commited suicide. the DREAM STATE brought him back and officially started the night he went out w/them. didn't you notice how suddenly everything went his way for a while? then the "dream state" had some glitch, and turned into a nightmare, he kept mixing the dream girl up w/the psycho one. in real life, he had been dead for 150 years. at the end i think he decided to be woken up, even though everyone from his life would be dead by then. he just didn't want to live in the dream state any longer. hope this helped.
