I see evidence for 2 interpretations, but what about the other 3?
Two interpretations have evidence: 1.) "Tech support" is telling the truth: 150 years have passed since Aames killed himself and subsequent events form a lucid dream, or 2.) The entire film is a dream, evidenced by the sticker on Aames' car that reads "2/30/01"
But what about:
3.) the events following the crash form a dream that occurs while Aames is in a coma
4.) the entire film is the plot of the book that Brian is writing
5.) The entire film after the crash is a hallucination caused by the drugs that were administered during Aames' reconstructive surgery.
