I wouldn't say that is psychotic, psychotic usually refers to people who hear voices, hullicinate and experience alternative realities.

Whereas with you, you have been watching tv, you feel you identify with some characters on tv, and in some of your relationships you've acted like, or wanted to act like a 'monster' whatever that means

perhaps you may need some counselling, perhaps you need to find a partner who you'll love and want to treat nicely, but this doesn't make you psychotic.
