C is for Cycle

Bruno sees a puddle of blood in his backyard, but ignores it. At night he hears a noise and checks on it, but finds nothing. In the morning, his wife Alicia disappears and he finds a hole in the bushes. He is sucked in and finds out he has been sent back in time to the night that he heard the sound; he was the one who made it. In the morning, he sees himself getting sucked into the bushes and is killed by another Bruno, making the puddle of blood seen at the beginning, initiating the chain of events that ended in him being killed as a causal loop.
