I came up with an idea for an RC, and it even worked for me once before in a dream (soon after that, I stopped, I'm not sure why) anyway, what you want to do is imagine writing or manipulating text on anything, anything at all. Close your eyes, and focus on what it is you want to write on (in your mind) and then imagine that your writing on whatever your focused on.
If I wasn't clear enough, or if this is confusing, let me know.
and lately, I've been kind of doubting this RC :( , I'm not sure why, but, what do you guys think, is it good?
