What is it called when your brain works faster than your body?
When a person has tachysensia, a rare condition, they temporarily experience a distortion of time and sound and have the “fast feeling” that time and space are moving faster than they actually are.
What is the sixth sense of human?
Proprioception, which is pronounced “pro-pree-o-ception,” is a sense that allows us to be aware of where our limbs are and how our bodies are arranged in space. Additionally, it aids our brains in world navigation just like the other senses—vision, hearing, and so on. It is sometimes referred to as our “sixth sense” by scientists.
