So, in my dream last night I passed a Lucid Dreaming Bookstore and thought "Hmmm, that'd be a pretty cool place to go, I'm interested in that.", then later a cafe for lucid dreamers. I even recognized that the slogan changed for it at second glance and merely thought "Boy, that's weird".

Any tips? I've been kicking myself all day for not getting lucid on that as I don't know how much easier a dreamsign could be.
