What is the weird energetic noise experienced in the ears by [name withheld]?

This is a kind of thought form being generated by the subconscious mind in response to prior trauma, so it is akin to an auditory hallucination of a voice saying dark things. In this case, it is an annoying sound that is meant to command attention and to disrupt things and it is a kind of desperation, much as a baby’s crying serves in order to get attention and to be disruptive if need be. This is not dangerous and will fade with time if ignored. This can also be dealt with via subconscious channeling as you are wondering as you ask your question, and would be a great exercise to take on as it would yield a quick resolution and be a feather in your cap, so to speak.
