When Time Slows Down

Do you ever experience the sensation that time is slowing down for you?
E.G. Your brain and motor functions are moving at normal speed, but
everything around you has slowed down?

I've had this sensation more than a few times. A couple of times when I was
in auto accidents (not my fault) and could see the whole thing slowly
unfolding around me. Another situation where things seem to move in slow
motion is when I'm riding as passenger in a light airplane and we're in the
landing phase. Approach and touchdown seems to be in slow motion when
someone else is flying.

Occasionally, like this evening, I get the slow-mo feeling when I'm landing
the airplane. The white stripes are passing slowly, the airplane is gently
settling towards the runway, and I can pick whether to land on the left
main, right main, tailwheel, all three at once, or any two of the three,
with the third to follow whenever I want, and the airplane seems to be at
taxi speed as soon as I touch down.

What's up with that, and where do I sign up for more?
