Our internal maps of our bodies don't always accurately reflect what our bodies are actually doing. And sure, this could be dysphoria related -- reducing our acceptance of external feedback, for example. But I think it's more general than that. Golfers, for example, might "feel" their bodies doing a thing -- like keeping the left elbow straight during their swing -- but video evidence proves much to the contrary.
Some "mirror work" might help. Play the drums in front of a mirror, for example, but rather than relying on your internal proprioception to create a certain objective effect, go strictly by what the mirror says. When you achieve the desired effect, notice how that actually feels internally. And then you could, for example, put the mirror away, turn on the video recorder, find that brand new memory of a feeling, and replicated it. Then look at your feedback and see if it stuck.
Quite often, the feedback of other people -- especially when it's near a consensus -- is more accurate than our internal perceptions, at least when it comes to our externalized performances.
