^ That's an interesting point. I've often wondered why certain dream signs tended to cause me lucidity easily while others simply seem not to despite their frequency. I think this may be the reason. For instance, seeing certain light fixtures act odd (or not being able to turn on lights of any kind, even battery-operated ones) usually make me start thinking, “This is getting odd. Is it another dream?” But I hardly seem to recognize when I'm in, say, my old childhood house again, which probably makes sense because I'm not usually thinking much about where I am in waking life, either, when I'm at home.
