During moments of danger, the mind (which is normally active and thinking all kinds of thought of past and future) stops. Thus there is a silent alertness, a clarity of vision and other senses. For such a person, it is as though time has stopped. This is something which is quite common in the meditative practice of remaining in the present moment. Eckhart Tolle talks about this in "The Power of Now". The Buddhists (incl Zen) talk about being in the Now, too. No, the brain does not speed up, and no, you do not start remembering each and every detail of what you see and hear. However, the clarity of the senses is remarkable. Its like one has been looking from behind a dirty window all one's life, and now someone has washed the window.
