I BEG TO DIFFER WIKIPEDIA

Memory Alpha goes further:

As mentioned in the Star Trek: The Next Generation Companion, this episode is considered to be one of the weakest of the fourth season and many members of the production staff were unhappy with it. The scenes with Troi “flying” were said to be a “terrible” mistake by Jeri Taylor and Robert Legato described them as “horrible”. Marina Sirtis commented that her desire for more action scenes had backfired; she had to grapple with an intense fear of heights in order to film them. Sirtis recalled, “The terror on my face was actually real. I was absolutely terrified.” (Selected Crew Analysis: Year Four – Crew Profile: Counselor Troi, TNG Season 4 DVDspecial features)

Jonathan Frakes remarked, “That was a yawner, wasn’t it? That was a shitty piece of special effects work when Troi was flying with those cloud[s] around her. That was below our standard.” (Captains’ Logs: The Unauthorized Complete Trek Voyages)Marina Sirtis opined, “I liked the storyline of that episode because it was about the dreamworld, and I’m of Greek descent so I totally believe dreams mean something. And not the Freudian thing, all this hocus pocus. So that was another one that I could relate to really strongly. But I did hate the flying.” (Selected Crew Analysis: Year Four – Crew Profile: Counselor Troi, TNG Season 4 DVD special features)

Rick Berman commented, “The sleep disorder was that our people were not getting enough REM sleep [and] they were all going mad which, in fact, is what would happen. It was all medically accurate, but it was kind of hard to follow and got convoluted. I don’t think there was anything very terrifying in it.” (Captains’ Logs: The Unauthorized Complete Trek Voyages)Michael Piller concluded, “[I]t was the first show right after Christmas hiatus and I don’t think everybody was quite back on their feet yet. As a result, the energy level was way down and the timing was off and the nature of the problem made everybody start reading slowly… The bottom line was that it was no longer a script because they were dream deprived. They were all talking slowly and after a while that gets pretty boring, and the middle of that show sagged and was slow, boring and disappointing.” (Captains’ Logs: The Unauthorized Complete Trek Voyages)

Director Les Landau blocked this episode out and prefers not to discuss it, for reasons he won’t elaborate. It had something to do with Troi floating in space. (The Official Star Trek: The Next Generation Magazine issue 21, p. 45)

I don’t know what they’re talking about I enjoyed that ep a lot.
