Is there a centre to experience? Listener question

I’ve been doing some exercises around the ‘headless way’ which involves noticing that there isn’t really a person looking ‘out’ at experience, there is just an expansive nothingness. Through the exercises ‘I’ have seen this, but the nagging question keeps coming back…

How can it be true that there isn’t a centre to experience when what ‘I’ experience is also unique to this body, these eyeballs etc.? If I was blind or deaf, I would experience the world entirely differently. Does this not imply that there is an ‘experiencer’ with unique qualities which then inform their experience? How can this be reconciled with the idea that there is only ‘pure’ awareness or experience?
