The speed of a thought is almost as fast as the speed of light or electricity. No need to take everyone back to modern physics class here, but the faster objects move, the slower time is with respect to them. Just as if you went in a space ship travelling at light-speeds around the Universe for 1 year and then came back to Earth, time with respect to Earth will have elapsed a 100 years or so more while you would only be 1 year older. Given this in theory, we could deduce that our dreams our merely a series of thoughts, where our thoughts are electrical current pulses through neural networks of the brain and nerves thereby travelling at almost the speed of light. Therefore, we could hypothesize that our dreams can last much longer because an almost infinite number of electrical pulses can propagate through the brain's neural networks within one nights sleep, let alone the theories of relativity.

This was good Shemsi and I agree with you and Breadfruit but for 107s question I don't think we can stretch it that far. No way of knowing I suppose, except that I can't do it yet!
