Dream Of Zombie Attack And Self Destruction

Is this one dream that I keep having every four years in the same time? Dream is very chaotic. It starts with me being a fan of a car race, which I'm at. There one car, I think it's number was 13, crashed. Oh, it crashed into a tree. It was going down from hell on a very skinny road. Underneath it, it was a river or it was on some kind of hill, I'm not sure. The racer who crashed was an old man. The whole car was lighted up and the man in the car was yelling for help. On the man, the tree he crash in the fall and he was stuck under the tree. Other fans who were watching it were yelling at me to run there and save the man. So I run to the road and try to save the man, but when I took off his helmet, I saw a skull of a man and he had a really disgusting face, he was like a zombie or something like that I was really scared and the man bit me and then the whole dream got blacked out. Then I was in my house and there were people around yelling that there are zombies trying to get into our house, that we should block it and go hide. My family was there, my mom, my dad, my grandma and her dog. Where I tried to hide, but everyone except me was eaten by the zombies. I end up hiding under my bed. Where I watched them being eaten alive, they were screaming and yelling for help. When the zombies left my room, I hid up on top of my wardrobe. Where I watched all the zombies being surrounded by the wardrobes around it, they were waiting for me to fall down and trying to get me. went over me. They... I somehow fell And they got to me and started eating me alive. It felt real alive. I really had a feeling that something was eating me up. They were biting off my muscles to the bone It was scary. It really hurt. I believe I was crying. I was yelling for help They turned me apart. They ate me, sucked my blood, and once they were done they left my body. I remember turning into a zombie because of them. I couldn't take it mentally. So, after a while, I saw if everything was devastated. Everything was abandoned. No one was alive left. Everyone who I knew was dead. It was just scary. I couldn't take it, so I took a knife and killed myself. I ended my life just like that. I couldn't live with how disgusting I was and what am I.
