Weird thoughts and dreams.?

OCD or obsessive compulsive disorder can produce violent thoughts. most times however the person does not take any pleasure in thinking them. at least after they've had some time to rationalize it. OCD can materalize in various ways and its different with everybody. I'd suggest you talk to your family doctor about your concerns and have him/her refer you to a pshychologist. the fact that your speaking about having these thoughts in this ways tells me that they are unwanted therefore you shouldnt just leave this alone and make excuses for yourself about why not to talk to a professional about it. Good luck! ^^
