What do you call demonic entity in the head ?

The concept of an "octopus spirit" or "marine spirit" is not a recognized teaching within official Catholic doctrine. Instead, it is a term primarily used in certain charismatic and Pentecostal Christian circles to describe a type of demonic entity believed to exert mind control and influence over individuals, often through various spiritual and physical vulnerabilities.

Within these specific Christian traditions, an "octopus spirit" is often described as a ruling demonic entity that operates with a central "head" and multiple "tentacles" representing various subordinate spirits or sins of the flesh. The "head" is frequently associated with idolatry or witchcraft, which is understood as domination, intimidation, and manipulation. The "tentacles" are believed to manifest as specific sins or negative behaviors such as lust, pride, fear, jealousy, greed, false doctrine, deception, rage, gluttony, and addictive patterns.

Proponents of this belief suggest that these spirits gain access to individuals through "open doors" such as secular music, gossip, witchcraft (in the sense of manipulation), and "pharmakeia" (a Greek word interpreted as the use of drugs or sorcery). They are thought to target the mind, influencing thoughts, perceptions, and actions, leading to confusion, double-mindedness, and a struggle against what is perceived as divine truth. The goal of such a spirit is to control and "devour" the individual, weakening their spiritual resolve and leading them into compulsive and destructive behaviors.

Deliverance from an "octopus spirit" is believed to require spiritual intervention, often involving prayer, renunciation of sins, and submission to Christ. The emphasis is on addressing the "root" (the head spirit of idolatry or witchcraft) rather than just cutting off the "tentacles" (individual sins), as the latter are thought to regenerate or be replaced by other spirits. This perspective draws on biblical interpretations, such as Ephesians 6:12, which speaks of wrestling against spiritual forces, and Matthew 12:43-45, which describes an unclean spirit returning with seven more wicked spirits if the "house" is left empty. It is important to reiterate that this understanding of "octopus spirits" is not part of official Catholic theology, which has a different framework for understanding demonic influence and spiritual warfare.
