In terms of healing the effects of human clients querying the repositories of human negativity, including thought plane, akashic records, and collective unconscious, does the collective unconscious of the extraterrestrials need to be considered? Do humans query the extraterrestrial collective unconscious or are they only affected by it as an indirect aspect of extraterrestrial meddling?

This is an astute question and a perfect example of your delightful thoroughness. You leave no stone unturned and this is a good thing. The issue is a somewhat complex one, but not for the reasons people assume. This is, for the most part, an issue for those involved with the extraterrestrials themselves, who have had interactions and know that the extraterrestrials can hear their thoughts, will come for them again, or are holding a threat over them demanding things in return. So it is very much a reality in their lives and very much an impulse within to check on what the extraterrestrials are up to, and to get a sense of things, much in the same way as the mind will reach out to collective unconscious of human to gauge the weather, so to speak or to see if there's anything new about oneself that has been deposited. So it is highest and best to include the collective unconscious of extraterrestrials for both steps of your process. Where not so necessary, they can be skipped over by the spirit team, so it will be no extra burden to include it and would be a loss, in some cases, although not many at present, to leave it out.
