A lot of people do accept the idea of a 6th sense though, some means whereby, from time to time, you get information that you didn’t acquire from your physical senses. It might be a “knowing” that you can’t trust someone, even though you have no logical reason to believe that, or v.v. come to that. It could be that “sense” of a place you get, that you really like or dislike it, without there being any obvious reason for it. These and many other kinds of examples are all about receiving information through your psychic senses.
