Dream of swim, kill me, falling

My uncle had commited suicide a year before. I had a dream I was the one that killed him. I didn't really see his dead body. I remember eating at a dinner. It was formal. Then, I went and killed my uncle. I went back to the dinner. I knew that the people sitting there knew what I had done so I ran away with his body out to a desert. I stayed there. A boy I like came and found me. I tried killing him because I thought he was going to kill me or take me back. He had just come to help me. I realized I had to go back so I hid him and went back. I hid his body in the roof and competed in a type of race. They were forcing me to race so I went. They split all the people into groups( there were a lot of people). I was in the last group. They let all the other groups start a little bit ahead and it took forever to wait for all them to go. Then, they took my group all the way to the end of the track. They took forever to line us up in our places and they waited a really long time to let us start. Finally, they let us. I finished the running part and the next part was to swim. I was doing fine. Then, I had to quit because I saw my uncle's body falling out of the roof where I hid him. I had to stop and go hide his body. My dream ended there after I fixed it.
