Lucid dreaming can have many uses. It can be used to overcome repetitive nightmares, stress issues, explore and discover whom you really are. I am currently researching (through my own lucid dreaming experience and knowledge) some more therapeutic uses for lucid dreaming. A few years ago I was a very stressed person, I had terrible anxiety that would arise from the silliest of situations. I believe it is through lucid dreaming that I have toned down and cured in a way the level of anxiety I have today which is far less.
