Donnie Darko

What the fuck is going on rn. I’ve never been more confused with a film in my life the ending makes no sense to me. Was he really dead the whole time? or is it the time travel thing?  My theory before looking at anything online(it’s gonna be dumb):  The bunny that he was hallucinating was really God and that he was supposed to get killed with the airplane turbine that night but the sleep walking saved him and he was given like a countdown or days to live and after these days where complete he went back in time and idk the heavens opened up and the air turbine fell on him and everybody forgot who he was like text said idk.  Idk why he shot the bunny or what grandma death symbolises but i’m just overall really confused. might rewatch  p.s. Patrick Swayzeeeeeeeee 😝😝😝😝😝
