To start you off, I highly recommend for you to read this thread. It is Puffin's Beginner's Guide to Lucid Dreaming, and will get you started right away!

A dream guide is a dream character who helps you and knows more about your dream than the average dream character; some believe that it is a manifestation of your subconscious.

We also have a section of staff called "Dream Guides" that can help you if you have any questions about lucid dreaming. You can find a list of Dream Guides here. Good luck!
