My client is feeling unusually anxious. Is this due to her spirit attachment I see? Can you give me some idea of the issue going on?

This is a human lost soul spirit she has picked up inadvertently and it is pushing some karmic buttons within her. Mostly, it is the troubled nature of the spirit that is transferring to her energetically. It is a double hazard. There is a resonance energetically, with having this consciousness within her energy field that is unavoidable. It is no different than the consciousness of her normal thought process, that when it is upset and under stress, it will create an energetic signature and that will affect the entire being, especially the deep subconscious that must worry about any possible threat to self-integrity and that will trigger an emotional reaction very quickly. The same will happen with another consciousness present in the form of a human troubled lost soul spirit. It will not be differentiated as non-self by the deep subconscious. So this is a deeper meaning of spirit possession. In effect, the spirit becomes a second consciousness on the scene, and as such, the person, in effect, becomes a dual being with two would-be captains of the ship, both with thoughts, feelings, and desires, and both will register on the deep subconscious and cannot be ignored. If the deep subconscious recognizes the presence of the wayward spirit as an intrusive energy, that will be helpful because it can then begin to resist somewhat any direct instructions from that consciousness. But it will nonetheless be seen as a grave threat to safety and personal integrity of the being, and this will cause a hue and cry to commence emotionally, with a ramp-up of the fight or flight response, depending on the severity of the discord coming from the spirit attachment. This is the best answer for her emotional struggle at the moment, because that is its origin, and this will resolve nicely with a clearing session on her behalf.
