Ive been having weird sexual dreams, that involve my older sister. Thankfully everytime it happens, I wake up before the sex starts. I dont know why Im having these dreams. I am 23, my sis is 32. I have seen her in bra and panties, so I know where the visuals come from, but I have never lusted for my own sis. Honestly, I never even tried to see her nude when I was younger. Am I a perv or something? I really dont want to have these dreams.

P.S. I have a girlfriend, I have sex regularly. I also share a house with my sis.
