Dream About Accident And Consequences

I dreamed that I was in an old basement and there was a man I know, and he was arguing with me and we were by the stairs when he tried to beat me, I pushed him off the stairs and he fell. I immediately recognized I was wrong for that but I didn't think with consciousness before doing that action and I didn't know whag to do, I got closer to him to check if he was still alive and I saw him breathing but fainted, so I grabbed his body but it was very heavy and threw him off the stairs again to make sure he was dead and make it look as an accident. There were some boxes so I placed them next to where he was laying but I saw there was a camera and I tried to cover the camera but I couldn't so I unplugged it and tried to break it, when suddenly my mother, brother and people i don't know arrived and found the man laying there and asked what happened and I acted as if i didn't know and acted surprised as if I just found out. Then my mother said "I will check the cameras" and I knew It was over. My mother walked away and went to check the cameras but when she got back she said she didn't find anything. I was nervous.
