I've also thought about the possibility of slowing time down in lucid dreams as a way of expanding each lucid experience. Like many have already said, our brains use conceptual thoughts in dreams...however, that in no way rules out the possibility of "slowing down" time in dreams.

In fact, it makes it more plausible. Using conceptual thought, we may be able to experience things in lucid dreams which seem to take hours, but in reality, it takes seconds. I base this idea on the fact that the brain can process information at incomprehensible speeds. Usually, our physical body simply cannot keep up with the speed at which our brain processes information. Fortunately, we have no "real" body in our dreams, so the only limitations on your dream body are the limits you place on it.

Using the high rate at which our brains work, it seems to me that not only is extending lucid dreams possible, but I think it will become a signifigant part of lucid dreaming in the future. A few decades ago, most scientists laughed at the idea of lucid dreaming......




.....who's laughing now?
