Becoming lucid, but just observing with the intent of memorizing the sub-100% feeling of a dream. Let's say this is done once for 30 minutes. In theory, I should be able to recognize future dreams based on that feeling alone. Anyone tried that before? If so, is it viable?

If said feeling when present was different enough to divert your attention from elsewhere than it would work. It's like any other dream sign.
