In love with someone i don't know

[mayax]

So you know when your on youtube for hours then you find someone seriously funny, yeah that happened and i watched his videos for hours!! Lets call him Jay
Now back on subject...

He showed up in my dream. It all started on a roof top with a bunch of 'Friends' (i don't know who they were) We were all hanging out talking watching sports. Me and Jay was just talking and his little sister came up, in the dream i seemed to know her as we hugged and i kissed her on the cheek telling her how much i missed her. We joked about before she went and hugged him. Suddenly one of the boys came up to me and sat down asking me what happened between us. In the dream we must have went out before. He looked at myself and Jay and said "Moved on already? It was just last week" He said in disappointment. Jay looked at me hurt then walking back inside with his sister. Suddenly i found myself in a studio apartment on the floor crying blaming myself for not telling him about my ex. I was about to walk into the bathroom to check my make-up when he walked inside the apartment with tears down his face. I ran to him telling him how sorry i was. He wouldn't look at me so i gently pushed him onto the sofa and climbed on top. We was about to make love when the dream stopped.

Please please tell me what this dream meant, i don't understand i've never been in love or had a serious boyfriend. It's crazy how i didn't know 1 person in that dream.
P.s i'm 17 btw

thanksss!!
