I had a dream about having sex with my friend who is a boy (like me) READ DESCRIPTION?

I have a girlfriend, and i had a thought about having a sexual time with my friend who is slightly camp, it all started when we became better friends and we were sat in ICT and i said joking around "if you dont stop it i will kill you", and another friend said "how", and i said "come into his bedroom and kill him", then my other friend went "eeeewww you want to go in his bedroom", to which i replied "no i meen...." and before i could finish my friend (the one i had the dream about) said "he has been in before for the night why not another time" (i have never been in the bedroom and he was joking around i think) then for some reason started to think why did he say that. Then last night i had a dream about me and him in the city centre alone kissing under a bridge and next thing i was in his bed having sex. But the thing is i am 14 years old, and in the dream we were about 19 or 20........... Is this just my mind playing tricks on me? Or is this my mind trying to tell me something, because i dont think i am gay, but i am only 14 maybe it just my hormones? Please help!!!!!!!!!!!!!!!!!!!!!!!!!!!
