My strongest experience of something like this was always when half-asleep on public transit, commuting home in the evening. Those rare times, I was indeed "tricked" by what amounted to a lucid dream.

I knew I was on a bus, because the sounds and feelings maintained continuity with reality. But the details I saw were completely made up. My eyes were closed, I think, but it didn't feel like that was connected to my ability to see. Because of the swaying motion of the bus, I knew where we were, and the scene I was "watching" was based on that. I was able to move, and think normally about my day, and did not notice that I had fallen asleep.

Of course, I eventually woke up. Reality was significantly less pleasant than my dream. The dream bus had been much less crowded, and clean, and generally more atmospheric and warm-toned, even the sunlight.

Does that sound similar to what you meant by trance consciousness?
