I think there's a lot going on when we dream, and it's not all directly related or cause and effect of a single process. The idea that a twitch causes a neurological response that we interpret as a part of a dream sounds nice, until you ask yourself why sleepwalkers act out dreams. They're not twitching, their minds are wandering and their bodies are responding. I have a feeling the guy is on to something, but I don't think it's quite as simple as "the reverse of what we thought is true". I would think the body and mind take advantage of downtime to do all the things they need downtime to do, and it makes sense evolutionarily for them to multitask so as to spend the least amount of time incapacitated as possible. So probably, many unrelated or tangentially related things are going on, and possibly even some hokey shit for good measure.
