Do the aliens have any ability technologically to alter the energetic signatures in the akashic records? Is this another way they can mess with us?

This cannot be done. While it can be reviewed and perceived in detail by the extraterrestrials, given their psychic ability, the records themselves cannot be altered unless they are personal events of the individual. A simple review of past trauma intuitively, that triggers inner emotion in observing the prior dilemma, may well add more negative energy into the mix because that process of review is a real-life event and, as we have taught, everything that happens goes on record. This is an important insight about how things work as a consequence of inspection. People change things for the worse all the time in their past history by the actions of their deep subconscious going out to survey what has gone before, seeing something unpleasant, and then worrying about it. That can magnify what is on record because it is the energy of the individual, after all, and is connected to them via cording, so there can be an interplay between the present and the past as well as from the past to the present, and both past and present to the future and back again. This is why those who worry a lot will typically continue to do so because they are worsening things, and they will not improve on their own, given the inclination to agonize over them in a harmful way without realizing it is compounding the damage. This also explains why much would-be talk therapy often reaches a dead end. Many people will drop out, even after a first visit or within a few sessions, after talking about their problems in the absence of a true healing resolution because it will stir the pot, it will bring up old business back to awareness on multiple levels of the mind, and this will reawaken old feelings and, in thinking about whatever dilemma they can recall, going over it, describing it verbally, will revivify what took place and trigger new emotion, and that negativity will be added not only to what is being unearthed via the memory being recalled and experienced in the moment, it will radiate out via the cording to the akashic records to add the negativity of that recollection, intended to be therapeutic, onto the pains of the past on file in the akashic records. Thus, the would-be therapy makes the problem worse. So this is a delicate undertaking and, if not done in the most effective fashion, will be a mixed blessing to revisit the past even with a well-meaning therapist.
