The concept of loosh as an emotional energy harvested from humans originates from the out-of-body research of Robert Monroe.

In his book Far Journeys, Monroe described receiving a telepathic transmission about a substance called loosh. This rare and highly valued cosmic commodity is generated through intense emotional states, conflict, and physical suffering. According to Monroe's accounts, higher-dimensional entities artificially seeded life on Earth to cultivate and harvest this energy, treating our planet as a functional farm for emotional output.
