The sixth sense is the common name of the standard name "extrasensory perception" (ESP for short), also called "mental perception". This ability can receive information through channels other than the normal meaning, and can predict what will happen, which has nothing to do with the inference accumulated by the parties before.
Ordinary people's senses (five senses) include eyes (vision), ears (hearing), nose (smell), tongue (taste), skin (touch) or other senses familiar to science today. Because the definition of senses is vague, so is the definition of extrasensory, but it is generally believed that extrasensory refers to information unfamiliar to science today, and these abilities are similar to the magical power of modern research.
