By "feeling" I mean qualia, not emotion.

You have just told me: "sometimes I wake up and I have the qualia of ___". But children wake up and say, "I woke up and have the qualia that I was never asleep".

So, how do you check? Why, by testing. Does the child respond when you call their name quietly? Can you pick them up and carry them around past dessert without them reacting?

But you don't offer, "Daddy, I saw the cherry pie but I was pretending to be asleep," which would be a compelling counterargument. You offer, "but it really seems to me that it is this way", and "I use my whole mind" and other rhetorical moves that attempt to dodge the need to actually seriously challenge the assumption.

But our brains aren't terribly high-fidelity when it comes to this sort of introspection. Your vision seems continuous and smooth; it's not. You taste aspartame as sugar even though it's not. There are significant neural connections to your intestines, of which you're almost entirely unaware. You can't tell when you hear a sound off to the side that you're actually timing pulses that race each other into the center of your head from each of your ears. People answering moral purity questions give higher scores (more morally pristine) when standing next to hand sanitizer.

Trusting introspective intuitions is foolish. I don't trust my own because there is abundant evidence I should not. I certainly have no cause ot trust yours. I trust that you have the qualia that you report--just not that the content of that qualia comports with reality.
