Nah, they're harmless. But, actually, a girl was talking to me once about how she heard from another lady that becoming lucid was like experiencing a "full body orgasm," and sought confirmation. I, being unfamiliar with the female experience, thought about it for a minute, and, yes, I'd say that's as good a way as any to describe it. Lucidity already appears well attached to its own versions of euphoria.

This may be a bit off-topic, but are you ever aware of certain feelings and vibrations that specifically occur during dreams? These used to be obvious markers of lucidity for me but they have since fallen to topics suspect for byproducts of intoxication.

Perhaps the best thing is to find an uncompromising ground. A decisive understanding, impenetrable by memory loss. Not derivative, but axiomatic. "No, I don't do drugs, this is a dream sign." Here the axiom being "I don't do drugs," which would not be derived from a lack of desire to get toasted or anything in particular, but "just because I don't." Lucidity would therefore be a derivative event.

But there could also be axiomatic signs for lucidity, such as those feelings and vibrations I mentioned above. "This is a dream sign just because this is what a dream is."

That would be an interesting discussion to have in another thread, I think. Whether it is better to have derivative or axiomatic dream signs, and strategies for working with the two.
