How can I learn lucid dreaming?

Well first you should do a little research HERE then try out what you learn. Then when you find any problem you may have you can ask more specific questions, in the group. Its a huge subject that cant be answered in just 1 paragraph and will differ from person to person what they need to focus on.

You could of course go to the "who's available" tab drop-down menu and book a lesson too, from one of the instructors found there.
