Grima
"Grima" you might not heard of it, but it is the feeling of "shivering", "chattering of teeth", "unpleasant sensation" whenever hearing a fingernail scratching on a blackboard or scratching a fork on a metal plate.

Base on my research, the feeling of "Grima" is also associated with our ancestors. The frequency that we hear that becomes grima are also the same with the frequency of the warning cries chimpanzees. The researchers says that our reactions to these sounds inflicts fear that becomes our predator-fleeing instincts.
