Non-erotic wet dream

Last night i had a strange dream, i don't know if i should call it a wet dream, because it had no erotic elements to it. In short i was alone, standing on the top of some building, and feeling sudden burst of happiness, like when you have an orgasm, and i suddenly woke up with erection and little liquid coming out, i don't think it was semen, it's probably pre-cum. Did some of you had this kind of dream and what do you think is the meaning of it? I think is just body trying to get rid of something, because this last week i had zero urges and no erections during the day.
