When i say in my head something like "i'm gonna go touch that bench" or anything really, i have to do it. if i told, it bothers me. is that normal?

If I understand you.: You sound like you are describing an urge that will not go away until you give in to it. I'm not sure about the word 'random' - but if I get you, that's sometimes seen as OCD - obsessive compulsions. It's not always terrible, but it is not normal. As it bothers you, I recommend good OCD therapy - maybe w/ medication if needed. You can get it turned around, but be patient. Get help - it's there.
