Lake

This dream is pretty fragmented. I am some random person, not myself in the stream but I'm at this lake with what I suppose are my friends. You have to walk down this big hill to get to this lake and it is somewhat of a steep downward climb. When we get to the water it is extremely clear. You can see lots of neat rocks. It's not a Sandy beach. So we start looking at the rocks and walking around and on the left side of the lake is where it kind of opens up more. I don't know if it is to open the ocean or it just opens up expanding out the lake even more. There's also these really fancy rich people houses all along the cliffside and by the dock More people seem to be on the left side while we stay on the right. As I was watching the water my friend had jumped in and he had gone underwater and then he just didn't come back up. at first I thought he was just swimming someplace else. Then I realized he was drowning. I jump into the water trying to look for him, and suddenly I can't see even though the water is so clear. I'm able to find him now and we pull him back up and I swing back to shore. Later he jumps in again and a big turtle comes up. I don't realize it's a turtle at first and it moves like it's a wave and crashes into the guy forcing him back underwater. At first, I didn't realize it was a turtle and then somehow I was able to zoom in and replay the scene again and I can see it was a turtle jumping on top of him. After that I couldn't find this guy again. And I start panic searching and asking people for help but he virtually disappeared after a while. I start heading back up the hill and getting to this van , apparently I live in this van. As I live in this van. I think I switched to being a different person. However, I'm still wondering where my friend went so I go inside this giant mansion house up the hill and it's pretty empty and vacant. It's old as well so it has that haunted feel, and it's multiple stories. I ended up going all the way to the top to where this tiny room was at and somehow I was told that I was going to stay there. The room was full of junk and there was another guy in there who apparently I knew. We start talking and it appears he's some kind of teacher to me, and he asks me questions about some assignment that I have no idea about which makes him upset. I tell him my story about the guy who drowned, and he said oh that guy is fine. Fine. That guy went off with other friends to do other things. I was pretty upset cuz I thought he died and we were looking for a long time only to find that he just left and didn't feel like telling anybody. I tried calling him but got ignored, and another friend called him and he picks up and said how he just wanted to get away and that I annoyed him and that we're not really friends. After that I don't really remember much else of the dreams
