But more abstractly, consider two events that are separated in both space and time, A and B. Let's say A happens first and "causes" B. Maybe A is "someone throws a ball" and B is "someone catches it." In any case if B is outside of the light cone of A, meaning that light or anything slower could not travel from event A to event B, then there is a reference frame in which events A and B happen at the same place. But when you "boost" into this frame of reference, you'll find that B happens before A. Faster-than-light communication implies that effect can precede cause.
Suppose there's a game of FTL baseball. I'm sitting in the audience, and in my peripheral vision the guy next to me get hits by a ball literally coming out of nowhere, while I'm looking at the bat swinging towards that same ball on the other side of the field... it hits and the ball vanishes (say enters Hyperspace). That doesn't mean the impact of the ball happened before the hit, I just saw it happen before the hit because photons coming from the ball next to me reach my eye faster than the ones from the ball being in play across the field. So I know the result of the hit before I see it happen. There's nothing wrong with that.
Now also suppose we can "rewind" the entire universe, and replay the entire event, while you can be a ghost present at any location in Realspace and experience events like you've always been there. Say there's a "ghost" of me sitting right at the other side of the field. Looking through the ghosts eyes, the bat hits the ball, the ball vanishes, then rematerializes hitting the guy -- a lot sooner than expected but not before it vanishes. The ghost can see it no sooner than a photon hits the ball and travels back to the ghost eye. Rewind and put the ghost smack dab in the middle, the ball vanishes and appears hitting the guy at almost the same time.
Finally, you can be the ball... you're actually a 360 degree camera that can take Realspace snapshots. That bat swings towards you, then bang! Looking back, you can see yourself, in the past. The bat is just about to hit you. And the next snapshot is a little bit further in the past as you're farther away from the bat about to hit you. It looks like time is going in reverse. Then you pop out of Hyperspace, hit the guy, but looking back time reverses again and is back in forward. You see the bat swing, hit you and see yourself vanish. Then you can see yourself, just a few times and for minute fractions of seconds, as you get closer and closer when you took those Realspace snapshots.
