how to get the real you?

Hey guys, I havn't had a lucid dream yet but I have a question. I have long hair right now, past my shoulders but in my dreams my hair is short like it used to be. Why is this and how can I get my current image of myself to be the me I see in my dreams?sorry if thats confusing.

Interesting subject. I dream of myself as a teenager, and this is because I still feel the same way as I did back then.
Do you still feel the same as you did with short hair? Did you prefer yourself and your life back then?

well, back then i had more of a social life, now im homeschooled and dont have to many good friends anymore. maybe that why. But its weird last night I drept that I had long hair. I think maybe cause I brought it up that my mind may have picked up on it and gave me long hair in my dream.I dont know though.
