i had a wet dream of my guy friend

I don't understand I've known him my whole life and never been sexually attracted to him or any thing of that sort but last night I went to sleep and had the best dream ever and I imagined us in a relationship and stuff doing stuff and I woke up this morning smiling and super happy and I'm mad at my self for feeling this way about him I know he doesn't like me he has a gf and everything I feel horrible but the weird thing is everything I remember from my dream I never saw his face just a guy with a similar build (I don't like him at all in this way)

excuse the shitty spelling!!
