falconfan, Donnie isn't on the golf course because of Frank. Frank is on the golf course because that's where Donnie ended up. Frank is a time-traveling ghost. Donnie is on the golf course because he's a sleepwalker, and has other mental problems. He's heavily medicated for some of them.
The sleepwalking means that Donnie doesn't die in the original timeline. Frank informs him of what he did in the intervening days, because Frank remembers it (ghostly omniscience). Donnie takes this as instruction, because he doesn't yet know who Frank is (and hallucinations would not be unusual for someone as messed up as Donnie).
Self-fulfilling prophecy is a standard feature of time-travel fiction (when it's done well). See The Man Who Folded Himself (David Gerrold) for a particularly nice gay example.
I think, falconfan, that time-travel stories are just not your cup of tea. They don't make linear logical sense, it's true. There's an awful lot of suspension of disbelief required. I mean, no one can ever change the past, because if they succeed they won't go back to change it, right? Would you go back in time to make Napoleon lose at Waterloo? He lost! So there's always a logical paradox inherent in ANY time-travel story that involves trying to change the past (for an example of a great time-travel story that doesn't, read Connie Willis' The Doomsday Book. Expect to have your heart torn out though; that book is extremely moving, and very sad things happen.
If that suspension of disbelief is more than you're willing to do (and believe me, I could understand that), then you're unlikely to enjoy time-travel fiction in general, and DD in particular. But right now you're doing the equivalent of saying "Gandalf couldn't do that! Magic doesn't really work!"
