Still, one wonders about the data. People who know what the term 'Lucid' means know that it is better to have a Lucid dream than a non-lucid dream. Toward the end of a sleep session, when it looks like no lucid dream occurred, what harm is there in saying that one had a lucid dream. As you said, the study DID indicate an almost unbelieveable rate of Lucidity. It seems similar to the Masters and Johnson Sex interviews from a few decades ago where eventually it became very suspect that people were lying about their sex lives (NO! Who would ever lie about sex?)

The only way to know for sure that a person has a Lucid Dream if for that person to give an actual pre-arranged signal with encoded eye movements; for instance, two flicks up, two flicks down, two flicks left, two flicks right. That would verify an actual Lucid Dream. But just asking people who want to glorify themselves in the Mantle of Lucidity is to simply beg for heaps of false data.
