I'm not getting the feeling of a ghost. For one thing, attached ghosts to the living don't spread out to multiple persons at various distances, in different locations. They affect the living host and their behavior. Maybe those behaviors will affect those close to them but in the normal sense of relationship dynamics.
What I'm picking up is a thought form, specifically what is called an egregore, a very dedtructive one. Egregores are created thru group thought, human thought. They are astral but feed on our plane of existance.
The fact is so many cut themselves nowadays, and it's not just young people that do this. It is more noticeable in youngsters because they are observered more closely.
I'm leaning toward the idea that the whole business of cutting is one huge egregore but maybe this one was created by S...or the S.O.B. that coerced her into cutting in the first place.
Let me give you a little background on egregores. They are created thru human thought, thru groups; they can be positive or negative.
They can be created in places of worship [any type], thru corporations, nations, any type of groups. They can be protective or destructive, helpful or harmful. If left unchecked, they can get out of control and take on a life of their own. They can take any form, memes and ideas are included.
"The more these ideas are called upon or repeated or reinforced, the more powerful they grow, and the more likely they will become something beyond mere thought."
"Examples of (possible) egregores include:
Corporations – brands, logos
Shared ideas – memes, urban legends, the Internet
Nations – flags, culture, patriotism
Spiritual or other group beliefs
Paranormal entities and experiences – it’s possible that many of the paranormal experiences people have, such as NDEs and alien abductions, may very well be the result of a collective consciousness thoughtform."
"As you can see, egregores don’t need to be “conjured.” They can manifest over time through sheer awareness and acknowledgement by large groups of people. You need not be consciously aware to participate in the creation of an egregore."
Aside from all the psychological reasoning behind cutting, it is an addiction to relieve emotional pain. So it's possible the the person who made S do this was doing the same...or they conjured something up and put it after her. Was this person into occult magick? In any case egregore or not, it is demonic. And S is a vector to spread this malignancy.
You all were trying to help S and it retaliated. But, you all seem to have experienced some type of trauma and this causes splittered off, unhealed parts which can attract negative entities.
*I'm having a hard time explaining much of this so please ask if I'm not clear enough.*
Clearly you are all losing vital life force. [the eating but still losing weight, fatigue...]
Your dream was interesting and I think I have an idea what happened:
"A night or two later I was having a normal dream, and then I felt a dark/cold presence behind me and the people in the dream noticed it. I knew it was this thing I'd been seeing and named it, and when I did that it jumped on me, and I woke up into sleep paralysis. I felt myself drifting, I still can't tell if it was me drifting back to sleep or drifting entirely and this things was taking root... It terrified me so bad that I started allowing myself to feel any strong emotion I could, mostly anger, until i got out of the sleep paralysis. I haven't had issues with this thing since."
What happened here was an encounter of two opposing thought centers; yours and its'. The paralysis and feeling of drifting was actually time being sort of frozen, 2 opposed thought centers, nether gaining ground...Until, you made a choice. Your choice was to reject this thoughtform, manifested thru your anger. Good for you; you won that battle!
I think your initial repulsion of S was a good indication of your healing and strong spirit yet you say she intrigued you. Might as well say drew you in. Be carefull of this, sweetie, trust your gut intuitions from now on.
That's all I have for now. S might be beyond your help and she might be vindictive towards your relationship with G. As for you, G, and G's brother, resist those harmful impulses with all your might. Hop-daddy gave you some ideas to help with your vibes. My advice is to become aware of any fractured parts of yourselves, get some talk therapy, if you feel you need help. Root out any thoughts, emotions, behaviors, desires, etc that feed/attract this thing and be vigilant about doing that.
Strength and power to You...Listen to the voice of your soul.
