Can a hypnotist assisting a client in doing a past life regression foster a connection to an interloper inadvertently? If so, what percentage of the time does this take place?

This is much less likely to happen than a desire to talk with the higher self or to another entity such as an ascended master or an archangel. The reason is that the mind is not going into the higher realms in such a direct and obvious fashion when one is simply looking at their akashic records, so this takes place frequently by the deep subconscious mind of each human being. During the day to day experiences of life, the deep subconscious is always referencing the archives to see what has happened in the past, what it knows and can learn from all that has happened heretofore and is looking for patterns and drawing inferences from all that is discovered. This is a broad outreach done on a continual basis and it is automatic. It takes place through all thoughts deposited in the individual thought plane. Those energies go out to the akashic records as well as the collective unconscious and this works as well across species in doing both. It is an attempt to learn as much as possible about what has happened heretofore that can influence things in the current life experience to take them into account and avoid entanglements if there are dangers involved—it is a survival instinct and is quite robust. So you have nearly eight billion humans all talking at once with the akashic records whereas very few are doing an intuitive outreach, so there is no particular advantage in the extraterrestrial psychics tuning into each and every human being to monitor all such intercommunications. They are more interested in the ones wanting to reach out and interact with a higher source of knowledge and awareness and that they want to block and are doing so actively. If they go into the deep subconscious, it is to deliver propaganda of their own. Anything that people learn from the akashic records about their past will more likely undermine them than uplift them because human history has been so challenged and difficult and there have been so many woundings across the board, so many truncated lives and lives of suffering and misery. So this serves the Extraterrestrial Alliance quite nicely—that all humans connect to, in that way, is dark information for the most part that resonates and will be a source of stress to undermine human happiness and progress. This is a large aggregate drain on the entire human community. Because there is so much preoccupation with past suffering, if only taking place within the deep recesses of the mind, it nonetheless has the power to undermine a person in very substantial ways. It is only because it is not possible to connect consciously to that level of the mind that the person is largely unaware of their inner torment. But it certainly plays out in the form of anxiety, fears, and other negative emotions that bubble up, seemingly out of nowhere, but are a major component of most people’s day to day lives and their interpersonal interactions.
