"Tachepsychia" is actually just part of the stress reactions that you might experience under great stress. Specifically, "tachepsychia" refers to a change in the perception of the passage of time.

Tachypsychia is a neurological condition that distorts the perception of time, usually induced by physical exertion, drug use, or a traumatic event. It is sometimes referred to by martial arts instructors and self defense experts as the Tachy Psyche effect. For someone affected by tachypsychia, time perceived by the individual either lengthens, making events appear to slow down, or contracts, objects appearing as moving in a speeding blur. It is believed that tachypsychia is induced by a combination of high levels of dopamine and norepinephrine, usually during periods of great physical stress and/or in violent confrontation.
