Why am I having so many dreams/nightmares about my crush?

It was random and the first time it happened but I have had so many dresm about this person, anyways I was walking into a really nice theater like the Beacon Theater or something like that. I was there for a concert. And so I only dreamed of after the concert. It was like three different hallways/tunnel/passageways to go down.So I passed one..the second one...they were having the Meet and Greet right down the hall. Somehow I didnt go to the meet and greet. And then I went down the third hallway and I went back to the stage and I finally got a setlist. Ive been to 5 of the same concerts where i was 1st row for a few and never got a setlist, I was always scared to ask. So I just went over to the stage..no one was on it..I snatched up the setlist and I also saw another sheet of paper, but it wasnt anything important..for some reason I took it anyways. And so a bunch of my friends were standing at a table I went over to talk to them. I sat the setlist down, finsihed talking, and I could never find the setlist anymore. I was so angry I was looking everywhere for it. I never found it, no one stole it. And then somehow I woke up in tears. I also had a dream yesterday that I saw him walking up the street i live on wearing a yellow tshirt with my favorite singers name on it and skinny jeans. Why didnt I say hi? Hes famous so he has other ppl hangin around him.. Hes so nice and honest and he doesnt fake anything. He has so many online friends but he talks to me the most. And he always has like smilie faces in whut he says and stuff And he teases me in a flirty way and he gave me a nickname a cute one too. And alot of ppl r jealous cuz he talks 2 me so much and stuff. And many of his friends are jealous cuz he talks to me so much..they like say rude things to me n stuff n their all ALOT older than me.And so as soon as we met up the 1st time he said with a huge smile come here and give me a hug. And we only got to hang for a day. So we went to this concert We didnt leave until 1am in the mornin and so as soon as he dropped me off at the airport i asked him could I have another hug and he said of course u can with a huge smile. We ended up huggin like 5 times that day! Hes sooo sweet! Every1 says hes into me and stuff and that he digs me only problem is hes 35 and im 19. Ive talked to him a few times! Every1 tries to hurt me and say he has a girlfriend..etc but he doesnt. Im friends with his friends and mom etc. Every night I cry myself to sleep. Im SO in love with this man its not even funny. Its 1:20 in the mornin and im cryin right now. I miss him soo much and i love him. He makes me so happy and everytime im around him I feel like a queen. Like nothin else in my world matters. All my troubles go away when hes around. When i see him smile and sing im just in a whole nother world. I cry so hard everytime i see him. He has taken over my heart and I wouldnt wanna love anyone else. When i hav to wait and see him the pain hurts so bad. Im always so depressed. My grandma is always yellin at me about seein him and travelin to see him. Hes 34. And im alot younger but im at the legal age but not the legal drinkin age(im not sayin my real age) I wanna love him. I wanna marry him. I wanna be with him to the very end. I would treat him like hes a king. Hed hav nothin to worry about. I just wanna lay in his arms forever. Theres also a slight race problem too. Hes white and im not. Im not black either. But my grandma is always yellin "What do u c in that ugly white man? I cant wait until the day he gets married. I just wanna call him and let him tell u he dont want u" Maybe its the grey hair that throws her off? She says stuff like that all the time. So I ran away twice to c him. I kno its a big deal but i didnt go THAT far. Im always listenin to sad love songs and just cryin my eyes out about him. Have i mentioned how nice he has been 2 me? He is always talkin to me online(its NOT his manager) and in person he is always huggin me and flirtin with me. I always hav the best time with him. And he always notice me durin his shows. The other day my friend sent me this video and she said dont look at it. I totally misunderstood her and I just busted into tears. I was shakin. I honestly thought I was havin a nervous breakdown. I was just cryin and I was very upset. Until i looked at the video and it was some song he was singin. She was tellin me not to look cuz he looked really sexy on the video. No one ever understands how I feel. This isnt a obsession. Or whatever they call it. This is love. I would die for this man. I never get along with my family because im always so busy findin ways to see him. Anyways im so tired of bein depressed. I even turned to alcohol a little bit. Can someone please help me? And just a heads up the guy i like is a celebrity but he isnt THAT famous.He won a reality show actually Is he just a friend or does he really like me? Help pelasee this is serious!
