In the year 20XX, Albert Psych released a case study revolving around brainwaves. Brainwaves are simply defined as the electrical impulses in the brain— the impulses that make up thought processes, encourage action, and form the imaginative capabilities of the brain. But all of those are just chemical reactions, sort of, and the case study further delves into that notion.
After much research and study of ancient writings, Albert Psych realized two things. One, that the mind is composed of something else which allows humans to have free moral agency. And two, brainwaves are literal waves just like radio waves. This means that it can be affected by other waves as well, and it could interact with other waves depending on the frequency.
