Creepy guy comes back from the dead and shoots me

Me and some random man (knew him in the dream though) were in a boat accident and the boat was destroyed and pieces were floating in the water. We were in the water as well. The man “died” and I watched his body float in the water. His eyes were bulging out of his head, and I remembered he had some scruff on his face, he looked super creepy. He like came back to life but his eyes were still bulging out of his. He started swimming after me with an evil grin on his face. I was terrified and swam away from him towards the land. He was right behind me and followed me on to shore. I ran but he pulled out a gun and shot me. Not sure if I lived or died but then like a new dream started but I was on the same beach. I was with my brother though and I just remember there was a giant pile of gravel that we were talking about climbing. The end.
