Why would you suggest ultra violet is not physical?
the mind, the emotions, our imagination and our dreams are not a part of physical reality
I don't see this as true at all. We can hook people up to machines and directly monitor how brain changes in physical reality directly account for these things. Have you seen the studies where even dreams can be interrogated on some level (and maybe even "imaged" in the future)?
I think what we previously considered "non-physical" eventually becomes known physically once our tools for measurement improve. To suggest otherwise is kind of silly to me because we have a history proving how everything we know is in fact related to physical phenomena.
It was not a "suggestion" but an analogy - basically that as we learn more, that which was previously not perceptible becomes so by the use of reason.
Correlation does not equal causation. Otherwise, we are pretty much "speaking the same language".
Even that which is (considered) non-physical/unknown can become known through its effects.
