Am i crazy to think these thoughts, paranoid, or normal?

Hi, i've been really depressed the past few days because of these really 'wierd' thoughts in my head. I'm not really thinking these things. It just comes to my mind because it knows its a scary thing to be thinking about. I come from a family of religion ( not too religious) but involved in the religion, and we take the religion as a part of our lives. Now in my religion it's really disgusting to think these things. To be more specific a thought would be running in to my head saying "God, why am i soo pretyy", or "what an ugly ass person, or i rule the world." I sometime laugh at these because there not my thoughts. There really not my thoughts. My sister said it was sub-conscious mind talking but it really scares me because i sometimes think im thinking these things and i can't stop them. Sometimes it haunts me so bad where i go like you'll turn disgustingly ugly or something bad will happen and god will be angry at you and teach you a good lesson. Other times i remember that it's not me thinking these things and that my mind loves to play mind tricks on me. I made an alter ego and named it capegoat, so whenever these really annnnoyinggg thoughts come into my head ill just be like its capegoat thinking this not me. I stopped with the capegoat thing because of the fear that i might go crazy. So now i just say to my self its not you thinking this. Just live on. This gets me depressed. Is this normal:(?
