Have you ever heard of it? Kind of like tachycardia, only it means ā€œfast mindā€: an altered perception of time, in which it seems to speed up or slow down.

Tachypsychia occurs under emotional distress such as an automobile accident. It can cause other immediate changes in our mental perspective too. For example, ā€œtunnel visionā€ and a razor-like focus on the threat at hand. Followed by ā€œauditory exclusion,ā€ causing distortion in what we hear.
