jealous ...

Last night i dreamed about him. It was so weird. It was strange. As stated by my dream, i was with him and then his phone rang. He picked it up then after a few seconds he hanged up. I asked him who called. He told me that it's his korean friend, IRISH. How come we've got the same name? I asked him. Then he told me "one day you'll see her." then the other day as i was walking on the street near his hous i saw him with the girl. I walked towards him.. Closely.. Now I can see the girl's face. In my surprise the girl looks like me. She really does. We have everything in common.. Name, face.. what else?!? I asked him who is the girl.. He answered "She is mine." My dream ended.. From the moment i woke up until this moment.. I AM JEALOUS.. i dont know why.. Why would i be jealous because of myself?
