Marrisa!

You've come to a good place to learn and practice Lucid Dreaming.

Lucid Dreaming can be used for many things; to have fun, to learn more about yourself, to solve problems, to face fears, etc. There is no wrong way to use Lucid Dreaming. Like sora said, how long it takes for a person to Lucid Dream varies, but it's extremely fulfilling when you have your 1st one.

Your friend that talked about her 1st LD; does she happen to have an account here?
