I had a friend, Colin, who was reading an article about the way our brain works in pressure situations. An example would be a potential car crash, where things seem to slow down similar to Matrix bullet-time.
Colin’s father was taught by his army buddies how to control his heart beat and said it’s kind of like flexing a muscle, you just need to know how to do it. Colin has a theory that you could learn how to control any of of your body’s physiological functions if you just knew how.
He wants to use Lucid Dreaming as a way to learn and control this particular bullet-time ability (as well presumably as other things like heart-rate and serotonin or adrenaline release).
