Okay i have a half brother who is older than me, i am 21 and he is 29, he helped raise me while i was growing up since my dad was never around. he is my moms child. We are very close. But ONLY as brother and sister. Last night i had a dream that we were making out. I woke up absolutly disgusted and still want to throw up from the dream. I know i dont have feelings for my brother like that obviously, thats wrong and disgusting but seriously why did i have this dream???
