How can I possibly choose an RC?

Toast, you’re right, as an RC that wouldn’t work very well. I’m not talking about an RC, however. I am talking about a state of mind. Those are the kinds of things you should ask while doing an RC. The point is to be aware of where you are and what you are doing during the day so that the awareness will transfer into dreams. Here, I suggest you read this article, The Secret of Frequent Lucid Dreamers.

If you still don’t believe me, talk to Wyvern who trained his awareness to the point he is constantly lucid in dreams :content:
