>>40674680I look at it like this. Consciousness is already non-physical. If you wish to test for it, observe that over the course of time there are two separate perspectives. A perspective is a unified collection of things existing together (coessent with eachother). Division in perspective interpersonally is what is meant by consciousness (although many people don't really understand what the term actually means and materialist philosophy confusing everyone is no small part of the problem).
Beyond this, there are many other things. Non-physical realities will inevitably seem subjective to anyone who used to thinking in terms of "physical (3-D object detectable with three senses) = objective"
The closest thing I can give you is physical phenomena that defy conventional explanations, but that isn't actually non-physical, just extraordinary and supernatural. For instance, the Mars effect in athletes is very "scientifically testable" so to speak. Another good example is the predictive capability of dreams, which I have a lot of personal experience with, but this cannot be rigorously measured because the dreams usually have thematic similarity to future occurrences rather than direct, but there is scientific research along the lines of telepathy. See https://parapsych.org/uploaded_files/pdfs/00/00/00/00/97/10_utts_assesment_of_the_evidence_for_psychic_functioning.pdf
These things just scratch the surface though because ultimately they still concern the realm of what is immediately measurable in physicality, just hard to explain according to modern scientific theories.
