I have brought up lucid dreaming to two of my friends on many different occasions.
At first one of them seemed as if they were genuinely interested so I showed him Dream Views but he sadly never signed up.
He told me that he read all of the material on the front page of the old forum set up though, and he talked a bit about that.
Just about a week after he read all of the information on the front page of Dream Views he told me that he had a lucid dream, and I seriously couldn't have been more happy to hear that.
After he told me about his first experience I guess he just got bored of the reality checks and such so we really haven't spoken about lucid dreaming since.
I plan on bringing the topic back up to him soon though, that would be awesome if I ended up getting him into it. People just don't know what they are missing!
