Is there any way to identify your dream guide as such? I don't mean calling yoour dream guide (here, either part of one's subconscious, rather than a separate being who may orr may not exist), but rather knowing which character or characters in your drams are supposed to be your guide, without them hitting you in the face with a giant mallet with "I AM YOUR DREAM GUIDE" written on? (yes, I do watch anime, why do you ask?) I've been using memonics for a while to try and summon my dream guide, but after doing so I pretty much always have a dream with a bunch of different characters, and if my dream guide is supposed to be one of them, my subconscious is trying pretty hard to keep me in the dark about it.
So, any suggestions?

(PS: One of my recent dreams involved being one of two observers of my lucid self, the other of which I could not see from where I was. It's in my dream journal, if that helps, or if anything helpful might be there. Link in my sig.)
