And the physical world in turn can act back on my consciousness. Matter, in the form of drugs, can be injected into my body and change my consciousness quite dramatically, even suspend it. So consciousness and matter are very friendly with one another. They interact all the time. That's one of the most obvious things about our world, yet it's seldom talked about.
Science has nothing to say on the subject.
Now, here's something else very odd. Consciousnesses can interact with matter readily enough. But they don't seem to be able to interact with one another. I'm sure, if it was at all possible, we'd have evolved to do it. But we didn't.
