A client whose husband abandoned her says he changed when his father died. When the father of this client’s husband died, is when he changed. Is there more to the story it would be useful to know?

As you saw intuitively, what resulted in the visible change in the husband’s demeanor is not only due to normal grief because he was so close to his father, but his father's spirit reached out to him after he passed and was invited in by the husband’s deep subconscious mind, and that spirit has remained attached to him ever since. Lost soul human spirits are never normal. They lack their normal faculties and are often emotionally in disarray and lack perspective, wherewithal, and a deep understanding of all that is going on and what is at risk, and so are essentially, both needy and helpless. As such, they are a negative influence on their host, particularly when there is a strong bond with a family member who has passed. That increases the stakes and will become quite disturbing and alarming, even for the mind of the host, to sense their loved one suffering and crying out to them and being helpless to do anything about it, even inform the conscious mind about what is happening. This results in a state of chronic stress, anxiety, and can lead to depression as well. It is likely to prolong the grief and drag the person down energetically, disrupt sleep, and so on. And they will not understand why they are unhappy but will, in fact, be feeling drained and miserable. The answer here is to do a Spirit Rescue for the husband’s father and that will remove that negative influence, as well as save that hapless spirit from further torment in feeling lost.
