A state of mind in which one
speeds up their own reactions to a point where their own sense of time is altered and the world around them seems to have
slowed. This causes the illusion that laws such as gravity have been bent, and the air around you feel like water, because you cant move or fall any faster than normal. People who can manipulate this can accomplish incredible feats that are seemingly impossible to do in real-time.
(Note:
Bullet time is measured in relation to the speed of a bullet, hence the name.)
