The subject stated that while he was receiving these questions, he was "dreaming that he was asleep in the lab".

Isn't is just as plausible that he wasn't lucid dreaming at all, and was instead in a half-asleep, half-awake stupor and responding to the questions from his awake consciousness?

It would be much more convincing if the subject were in a different landscape.

They verified via brainwaves that he was in the REM stage of sleep. I don't really know anything about brainwaves, but this seems like the kind of thing that's fairly definitive.
