HELP PLEEEASE

I need alot of help. most people i have contacted would not respond.
Well i was hoping you could tell me what this Dream means!!
Well it all starts of in a train station.It was very bright by the way.all of a sudden i find myself walking to the train talking to this very pretty girl. she is everything I would look for in a girl, and for some reason i felt like i have known her for a long time. so as we walk in to the train,(which was quite empty) and we sit down. she sits across from me, so I ask her "why dont you sit here"? meaning next to me. so she sits next to me and rests against my shoulder.I remember the sun was out to. as the train moves i put my head back, AND THATS WHEN MY sister woke me up!! the dream happend so fast. and for some reason i could never forget it! PLEASE PLEASE some one help and thx alot!!
