Strong Emotions/ Tied to a Dream?

Hey, last night i remembered alot of dreams, one of which really really got me feeling emotional. I was with this girl and her friend, this girl was really hot, though i can't remember what she looked like i remember that i found her attractive and we were walking along the side of a beach after i escaped from a crazy 19th century wacko headmaster. And we were talking she seemed like a hard person to ask out and i wanted to tell her my feelings for her but i just couldn't, and then later on in the dream i screwed it all up by telling a crappy joke in front of her and her parents, i think she was american, not sure, but i think she had to leave to go somewhere and due to my lack of conciouss descisions i couldn't tell her how i felt and i started getting upset in the dream and i awoke feeling really emotional, not crying my eyes out or anything but it was strongly on my mind and it still is. I feel asthough i need to go back into this dream and sort things out between us etc, i want to go back to this dream because i feel asthough i should however i don't know if i can do. Can anyone offer any advice on going back into a dream you've previously had, also, i can't remember her face now, when back in the dream will i remember her face? Thanks alot, i really appreciate any feedback!
