Yes. But qualia, subjective experience, state of consciousness, phenomenal consciousness, etc. these are not good definitions (as asked by OP). These are just all talking about the same thing without a proper definition that would allow us to define its different states. Measure, quantify, understand, sort, etc etc.

That seems a bit like trying to put a number to how hungry you are. "Experiencing a desire or need for food" doesn't even begin to describe the sensation, but that doesn't mean it's not a real phenomenon that can't be induced or adjusted in a fairly predictable manner
