In modern mythology, gloomy spirits are popular, traditionally called Galla (flyers), or the name given by S. King - Langoliers

The key point is their position in relation to consciousness, the Psychocosmos - if the Parasite of Consciousness lives inside it, then the Langoliers live outside, however, both groups of predators feed on the energies of consciousness, while if the Parasites of consciousness “force” to give up energy, the Langoliers feed on the fact that consciousness "lost"

Any active action leaves an imprint in the World passive environment - a Reshimo, which, according to the Law of Analogies, preserves the connection with the consciousness that gave birth to it, thereby interacting with this “imprint”, it is possible to interact with the consciousness that gave birth to it - including - and steal its energy, namely this is actively used by the inhabitants of the Qlippoth, deprived of the ability to generate Power

Like burying beetles that eat dead animals and prevent the outbreak of an epidemic, langoliers eat “dead” things, saving worlds from the invasion of Qlippothic entities and returning the Passive environment to a “pure” state, breaking the connections between consciousness and its imprints, according to the analogy given by S. King - Langoliers “eat the past”
