An egregore is a collective thought-form or psychic entity created by the shared focus, emotions, and intentions of a group. It exists as an independent energy form and can influence the individuals connected to it.

In esoteric and occult traditions, larvae are parasitic astral entities or thought-forms that feed on negative emotions, energy, or habits, often attaching themselves to individuals who resonate with their frequency.
