Blake Ross can’t visualise things like others:
I have never visualized anything in my entire life. I can’t “see” my father’s face or a bouncing blue ball, my childhood bedroom or the run I went on ten minutes ago. I thought “counting sheep” was a metaphor. I’m 30 years old and I never knew a human could do any of this. And it is blowing my goddamned mind.
My first thought was “yeah I’m pretty bad a these things too,” but then I kept reading, and I realised how much I do visualise in my “mind’s eye” that just seems alien to those with this same condition.
