Why do I crave foods I don't like?

This is something new and no, I'M NOT PREGNANT!! Somedays I'll crave random foods that I don't like at all. Like the other day I craved Pringles and then Frito's and Bean Dip. EW! I don't like chips in general but I especially hate Pringles and never have liked Frito's. I can't stand beans, but I ate these things anyway and it satisfied the craving. I also crave other things I hate like coconut and Reuben sandwiches. Seriously, what could be going on with me? Like I said there is NO WAY POSSIBLE that I am pregnant so what else causes weird cravings?
