Unless we are experts in a particular field, we get science through secondary sources which I assume are reliable descriptions of the actual science plus speculations about what it means. I don't know if that is good or bad. There is only so much any of us can be experts in.
I don't think there is a Freudian "unconscious". There might be a Jungian "collective unconscious", but the only benefit with that term is the additional collective adjective. Of course, I am no expert in psychology. I am just trying to philosophically make it possible for psi to be grounded in some theory. This would involve a global consciousness. Awareness is consciousness restricted to an individual member of a species. If consciousness is larger than the individual, then psi can be grounded in this global consciousness. It would also allow animals to participate in it as well. Empirical evidence from the senses would then be expanded.
