So I found this site googling around:http://www.entity-removal.co.uk/What-are-Entities-.html
Astral Parasite is a term I use to describe the many forms of energy parasites that feed off the human energy field. Like physical parasites they aren't usually especially 'dark', or even very aware, but they are hungry! Think of them as psychic leeches.
"These parasitical creatures are very common, but are unlikely to be noticed unless the host is sensitive, or they grow large or numerous. At this point the person's energy becomes compromised and they will most likely display some of the signs listed on the Signs and Symptoms page.
In my experience they take many forms, but some are more common than others. Here are some of the regular forms that turn up:
There is a tentacled parasite that threads into the chakras to feed and can reach out with tentacles to pull additional energy from other people around the host. Often people instinctively give the unfortunate host a wide berth because of this, or friends and family notice they feel drained around them.
I see a slug like form that feeds primarily from one or more chakras and can grow huge, eventually draining much of the host's vitality. I have seen this type grow so big it forms a complete a loop right around the person's chakra system going over the crown chakra, down the back, under the base chakra and up the front. People with this size parasite usually experience chronic fatigue.
There is very common jellyfish type parasite that feeds from chakras and a mulitple layered 'russian doll' formation that caps off the chakras.
I sometimes see black balls of energy that hang in the aura. If they multiply the person's aura can look a bit like Pigpen from Peanuts cartoon! As well as being generally irritant they can create holes in the aura which will cause the person to leak energy. Auric holes will reduce the natural protective function of the aura and may let more troublesome energies in. "
It goes into greater details describing serpent like entities that are even worse apparently. IDk, what do you guys think?
