We now see parts of the last 28 days rewinding as the TU starts to unravel. The TU has collapsed safely and the PU that was on pause starts back up from when it stopped. We are now back in reality on October 2nd, the last 28 days never happened. Donnie wakes up in his bed laughing after dreaming some of the events within the TU . He then goes back to sleep seemingly content with life now. The experience has seemingly brought him closer to God and he is no longer afraid to die. The jet engine Donnie sent through the time portal now falls into his bedroom killing him.
