I did a short presentation on lucid dreaming once in class, people seemed intrigued. Apart from that I have only met one person at my uni who is a lucid dreamer...It can be a good idea, but you need at least a few people on board to begin. Otherwise it'll be just you persuading people to join, can get pretty tedious. You could leave some kind of contact information (create a fb page or something) - post it to message boards around campus, or leave notes with the link to it in the library, asking to contact you if they are interested in lucid dreaming. Who knows, maybe there are like minded people indeed.
