Egregor

Egregore.  From Wikipedia.

Egregore (also spelled egregor; from French égrégore, from Ancient Greek ἐγρήγορος, egrēgoros 'wakeful') is an occult concept representing a distinct non-physical entity that arises from a collective group of people. Historically, the concept referred to angelic beings, or watchers, and the specific rituals and practices associated with them, namely within Enochian traditions.

More contemporarily, the concept has referred to a psychic manifestation, or thoughtform, occurring when any group shares a common motivation—being made up of, and influencing, the thoughts of the group. The symbiotic relationship between an egregore and its group has been compared to the more recent, non-occult concepts of the corporation (as a juridical person or legal entity) and the meme.

I am seeing it used somewhat in the context of ideology, i.e. a person is captured by the egregore of wokeism (or Social Justice Theory or Postmodernism or Critical Race Theory or Intersectional Theory).
