If one were to memorize the Lightworker Healing Protocol and repeat it in the dream state, would that make a discernable difference?

Any part of the mind reaching out for help will be heard. The difficulty is that the lower levels of the mind are not the most astute and capable of mounting an intention for high-level assistance to keep things straight and to know when and how to implement them. It is possible to memorize the Protocol within the subconscious, but the circumstances and the agenda decided on will be unpredictable because this level of the mind has an agenda of its own and this takes the healing work outside of the control of the person on a conscious level and that has risks. There can be many misguided notions adopted through belief incorporation by the deep subconscious. So it may well act on an inappropriate and misguided set of intentions with an agenda that is less than lofty at times. It is the part of the mind most easily corrupted so it is risky to trust it with a critical function like healing, so we would not endorse this idea.
