This is not due to reinfestation with spirits. It is simply that her mind has been programmed now to create fear of this and their presence and is recreating, in effect, some of the tormenting. This they always teach their host to do as it serves them to have the host self-torment to stir up negative emotion they can tap as energy without having to do work themselves. This is a leftover consequence of their intrusion and manipulation. It is unfortunate when this happens but it is very common and sometimes must be endured. It can fade on its own if it is not reinforced by a new spirit intrusion. This you can help to avoid through prayer work for safety.
The work of the Lightworker Healing Protocol is still ongoing and will be chipping away at this in addition to making every attempt to confer safety and protection going forward. It is still possible that a darker aspect of her mind will end up talking with the dark ones and allowing them to enter during the sleep interval as this is a common weak point for many people. The best that can be done is to keep an eye on things and check her at intervals to be sure she is staying clear. Certainly, any abrupt worsening of things is likely to be a sign of reinfestation. In the meantime, things should ease with further rounds of healing that are underway and planned.
