Egregore - Wikipedia

Egregore (also egregor) is an occult concept representing a " thoughtform" or " collective group mind", an autonomous psychic entity made up of, and influencing, the thoughts of a group of people. The symbiotic relationship between an egregore and its group has been compared to the more recent, non-occult concepts of the corporation (as a legal entity) and the meme.
