Hello, I have found a game online that can (maybe) help you with lucid dreaming. In a nutshell, you take the role of a girl that has odd dreams every night, you make her go to bed, and induce a lucid dream. When she has the dream, you are free to roam around the dream and collect things, and do various activities around the dream-world.
You collect things, explore different zones/areas, see things that you've seen in the "real life", and much more. Although, when the player wakes up, you must write in your dream diary (in-game) what you've seen in the dream, that helps you become more lucid each time. Anyway, the game is free and I think all of you would like to try it, it's virus-free and it is not that big of a file.
Scan if you wish, the file download link is:

Enjoy, and I hope you all check it out.
