Mind Parasite

The Mind Parasites are from Colin Wilson's "The Mind Parasites (fiction)".

Description

A great burning fragment had been torn from this sun by a passing comet, and hot gases had condensed into the moon as we know it today, gradually destroying its inhabitants. But since they were not bodies in the earthly sense, they could not die in the ordinary way. They tried to adapt to the cooling matter of their world, becoming a part of the molecular structure of the solid as they had once been a part of the structure of hot gas.
— Colin Wilson. "The Mind Parasites (fiction)"

Vague, incorporeal, invisible, intangible, gaseous entities, once a sentient gas dwelling in the Sun, the Mind Parasites were stranded on a cooling chunk of sun-matter that broke away in the form of a cooling moon, forcing the aliens to adapt the only way they could as the warmth drained away: as parasites on other living creatures, feeding on their victims' intellects of intelligent species, especially humans. Now, the Mind Parasites secretly infest almost every living human being on Earth, quietly drinking away a little of each person's intellectual potential, and driving to madness anyone who notices - in fact, many of Earth's greatest thinkers, artists, and visionaries noticed the parasites, and many of those thinkers, artists, and visionaries were also met with paranoia, anxiety, depression, confusion, madness, suicide, persecution and death.
