Scared Of

My brain keeps shocking me with different things. Like for some reason if I'm doing something nice or playing something all the sudden I get hit with a sexual wish regardless if its a family member which is disgusting, or having to kill someone basically my brain just shocks me with random wishes that I don't want to come true or imaginations. I calmed down with the thoughts but its still affecting my routine to do something to the point I just want to stay in bed because I'm disgusted or just don't wanna think about it. I have tried distracting myself but it always interrupts and ruins the game I'm playing. Anyways, tips to get rid of these thoughts?
