Like a yume nikki fangame? Or just a game about dreams but instead of having made up dreams it will be about the author’s actual dreams? If it is the second idea, I think it could be very interesting. Isn’t “LSD: dream emulator” made around the same concept? Anyway, I think it depends on the kinds of dreams you have and are going to use for the game, and the whole atmosphere you want to give to it. Are the plots and stories in your dreams able to hold to only one story, converge and follow a single plot? Or do they accomplish more by themselves, each dream having its own set of maps? Also, think about how you want the player to experience your dreams. And yes, this board is on its deathbed. Sorry for my English, I’m not an English speaker.
