"Subtle energy" is a specific term that is not the same as the description of a physical energy. I understand what the word "energy" means in the scientific sense, but do _you_ understand what the term "subtle energy" means? Subtle energy is something that can be experienced. Among those who do experience it, if it is a hallucination, it's a shared hallucination. It has something to do with consciousness. I have severe doubts it can ever be describable or disprovable with a controlled scientific test. That is, I thiknk there are limits to what the scientific method can determine. I don't think it is measurable, at least not with the technology we can construct. It is not electromagnetic, though some forms may be experienced as having electric or magnetic properties. But one property that is not described by physical description is that it carries information: emotion, awareness, sentience, in varying degrees. However, I know of people who have tried, though I haven't seen what they published about it. It is replicable: do the correct set of practices long enough, and you can experience it. (And this is why people freak out when those practices actually works). However, I don't think it can ever be objectively measured. Psychedelics can sometimes trigger the experience of it. With the use of microdosing and clinical applications of psychedelics becoming mainstream, I expect more people will start encountering this.
