Hahaha Me and My dreams...?

Okays so a few nights ago i had a dream about my sisters best friends brother who is only a year younger, i never thought about him at all unless if im actually seeing him, there was one day where i had no concept of this guy, and i have a dream about it, it was the weirdest thing ever, and so random, i tried to remember that day, there was no connection to sam, it was weird, What does it mean? Btw- no i didnt have a crush on him, but i did ever since the dream... :/
