How do i know if a boy really likes me or if its fake?

i have know a boy for about 6 years and he has never ever said a word to me.. but at this event for this company we had is boys kept telling me that he likes me but he never said anything to me for the 6years he has known me , he has never said fart to me. but now i think he does like me because when i saw him again , he was talking to some girls who were near me and he kept looking like he wanted to say something to me because he never talks t those girls hat i know of. and then i keep having these weird dreams about him , they re sexual Dreams we don't really have legit sex , but we are always touching ad feeling on each other the most we ever done besides that was kiss on this lips ,(this was in my Dreams) and another weird thing is that this last dream i had about him was about 5 days ago, was a setting at my school , we don't go to the same school!!! but were both in marching band, im color guard and he does drum line at his school, and i was getting ready for band camp , after i had finished my test in the library and that's where it started , i was taking a test and we were at the same table , and out of know where he started smiling at me and playing with my hand ,and then when i was finished we went to another side of my school to go get my flags,and sabers and stuff to put them in our marching band trailer. and then we walked each other home and we was all over each other like hugging and stuff like that. we really enjoyed each other company i guess.and it was just a really weird dream. i dont know what to do, because i dont know if his boys were playing or if he really dose like me or if im the only one that has feelings. and then his facebook status sed something about him wanting to be with this girl but other things kept happing . no i do not have him as a friend on facebook his profile is public and i want to add him but i dont want him to think that i added him juss cus of wad his friends sed. and they sed it hewas smiling and looked away. and then after that day he just seems likes he wants to tell me but idk what too do cus its hard to figure stuff out like dis.. i wish he would really tell me insted having his boys tell me ;( i dont kno what to do , b/c everytime i have a dream about him my feelings get deeper and deeper and i dont want to get hurt if i come to him first. please tell me what should i do :(
