Attachments can be a part of the following: elementals, Dead Energy, Fragments, demonics, earth bound souls, Negative Aliens, collective thought-forms, ancestors, Etheric Weapons, geo-pathic stressors (curry lines or static energy fields) and just plain bad energy (reversed life force) deposited into the land mass, in houses, places of worship, or any other space a person walks around on the ground. This kind of negative energy can build up in a person’s Aura and make one feel physically, mentally, emotionally or spiritually sick. This is similar to understanding if our life force and aura are not circulating properly we can have “clogged pipes” that make us feel un-well. If we have an entity attachment in our aura it can make us feel sick, slimed, and not ourselves. Most humans are not aware if a massive trauma happens on a land mass at any point in time, that energy is stuck there until someone cleans it up. If no one does, it lingers and attracts more negative energy. Generally this creates an unhappy space, and a sensitive or Intuitive Empath may feel this energy and want to run away from it.
Having clarity from within this massive confusion requires awareness of negative patterns and their attachments and then the focused discipline of your Negative Ego mind to clear them. It is the time to remove all attachments to the external outcome and personal results. 
Fragmentation causes Negative Entity Attachments
Additionally, when a living thing is tormented into feeling extreme pain or suffering, the mind and Soul can fracture into pieces, keeping those pieces trapped in phantom pockets that are controlled by that negative entity. This can happen at multiple dimensions of existence and stations of identity that are connected with the consciousness of that spiritual-energetic being. The more fragmented the being, the more disconnected and less evolved the consciousness becomes, until it sinks into the most primitive layers of existence. Fragmentation may continue after the consciousness has transitioned from the body. This is the primary goal of the NAA that attempt to enslave human consciousness, by eliciting pain or terror when exiting the physical body. In Satanic Ritual Abuse the rape, torture or killing of an animal or human is for the purpose of collecting the loosh produced during the blood sacrifice event, and to bind the energy with attachments, which can be fed upon by the black hole entities. They form attachments from the negative energy they consumed, to the fragments that make up the consciousness of that person. Many of these negative entities consume negative emotional energy to enable their presence in the multidimensional layers of the earth field. Because of their vibrational incompatibility with human frequency levels, they must rely on consuming Loosh for their existence.
The important lesson to comprehend is that expressions of Negative Ego and hatred, the intent to harm and the violent killing of other living things, fragments consciousness and feeds the reversals to build up negative emotional energy or Loosh. We do not want to co-create negative emotional energy to be fed upon by these negative entities or to directly feed the Inverted Systems that produce Loosh energy for the NAA. The most productive thing we can do is to take steps to clear negative ego and our Pain Body, so that we will not be triggered by the Mind Control programs or AI broadcasts. When we do this, we are instead capable of holding neutral and calm within the chaos.
We can practice unconditional love, peace and Harmlessness. This helps to integrate and heal our Fragments to unify, as well as neutralize any Negative Emotional Energy in the environment. When we stop feeding the energy reversals, they are gradually taken offline. The feedline of the parasitized energy throughout the food chain stops, essentially starving them by denying them access to the power source. When we can hold compassionate witnessing and refuse to be triggered into negative emotional states, we are refusing to be manipulated and siphoned by the NAA. Additionally, truly empathic and unconditionally loving humans may also gain the spiritual power to recollect and transit the consciousness Fragments of sacrificed children and traumatized people that are trapped in the earth realms, and this is an important service we can do to help heal the earth.
When we consistently think with the Houses of Ego we are using the Negative Ego which requires to consume energy from the external world and from others that we have developed Attachments. This is called the Consumptive Modeling of the Imposter Spirit and their related forces. 
The Witness or Observer has no judgment. It allows observation of external events without needing to control the outcome. By maintaining neutral one can release Attachments. Once a states of observation without judgment are easily held in one's Consciousness, the being will choose its continued evolution through the choices it makes in accordance to the Law of Compassion. Either one develops their higher mental bodies which are a function of the higher intelligence of the Soul and Monadic bodies, or synthesizes these mental intelligence through their open and loving heart. Compassionate practices open the closed heart chakra and its complex. Higher knowledge without practicing Compassion produces a Luciferian entity. Without compassion a being cannot develop any further in Consciousness and will expand horizontally, rather than vertically.
There are also spaces that are used as soul traps or Consciousness Traps, which are used to keep a person’s consciousness stuck like a hamster on a wheel, going in circles and not moving anywhere.This is why discernment and comprehension of how consciousness works and placing your value and attention on developing personal consciousness is so important. False White light and consciousness traps are like machinery, they are not fully sentient. Instead they are like replicants or artificial intelligence, which may be cognized when one has developed sensory ability and feeling through heart consciousness. When one has a connection with the 12D Shield and the heart and Spirits of Christ, you will feel the harshness of non-sentient or alien matrices immediately. They feel machined, artificial, metal like, sharp, may feel or sound "tinny" like an aluminum foil. When one is active in the pursuit and dedication of expanding ones consciousness, and knowing these consciousness traps do exist, you can avoid them. In some cases, you may even be a part of the grid work teams asked to dismantle them to stop other Soul’s from being trapped inside them.
To Mind Control the consciousness of the masses and control their perception is how slaves and drones are created. Humanity is cultivated to shape values and ideas that the Controllers have cast through the lens of the Predator Mind. Until the individual can identify and sense the Predator Mind construct, they are engaged with that lower mind and what has been created in deception and illusion to trap the individual into feeding into the Collective Consciousness program. Tyrants, Dictators and Despots through the ages have withheld information and even erase historical facts to retain power and control over who they seek to exert their rule. So the goal of the Archontic Controller is to keep the accurate history, knowledge and information erased and hidden - to deprive the right of liberty and freedom for every individual. By doing so they remove the ability for people to have the conscious choice to discern their personal energy and to decide where they ultimately want to place their consciousness energy.
