here is what I think happened

Simon Cable felt guilty in his REAL life ---and no one forgave him for his sins before he died...The fight with Peter falling off the roof really happened because that is what put them all 3 on the road at the same tragic time.

Peter and fiancee die and Simon is near death. (or does he die on the road?) He over-hears conversations of the paramedics as he is going into a COMA. or death... (he is not aware that the woman who hit them is the fiancee.)

From 2:00 am to 2:02 am, he has a "movie" playing in his mind. All the characters are people from his real life but it's only a dream-like state.
Cause if it was real life he was seeing, his dad (Stephen Rea) would not be the doctor! Right?

Peter is in the afterlife and comes back to help Simon by telling him to accept all 3 deaths. This visit was to get Simon to accept death (if you believe that the dead can come back briefly with messages). Peter has moved on and wants to help his brother.

But true hell is Simon repeating the same 2 minutes over and over for eternity.
In those scenes where Peter and Simon talk again, some things are not the same. This is a new version of his nightmare.

Discussing this move doesn't mean "I Inside" was all that good...just incredibly confusing.
If you want to see something REALLY confusing that will make you scratch your head, but ties it all together at the end, watch the movie STAY with Ryan Gosling.
