dreams?

i guess dreams tell me a lot of things. what in fact? when i finally knocked myself out last night/this morning, the first dream i had was me and her getting back together. not romantic stuff. just us getting along well like we did before this. when i woke up, i realised that it wasn't real at all and tears start coming down again. i woke up so many times during the night, and every time i do, i remember the situation i am in and i feel so sad again. i guess it affected me deeply. so deep that my subconcious/my mind made me dream about us. i guess it shows how much i want that to happen now. but i really am not sure already. how do i preservere if she has given up?
