Interesting interview with Maggie McCart, who suffers from Prosopometamorphopsia, aka Demon Face Syndrome.
I always find this kind of thing interesting as I have a bit of prosopagnosia myself — that's a general face blindness. You could ask me to describe people I've known for decades and I'd have trouble with the face and facial area. If I recognize you on the street — which I won't — it's actually due more to your gait and silhouette than your face. Bless you if you've got every day carry accessories: a cane, a satchel, a dog.
Anecdote Alert
I became aware of my issue when I was about ten. My mother didn't come home when expected. A couple hours later, I called the cops and when they came over, they asked me if I'd seen her that morning. I had. They asked me what she was wearing and I couldn't say. They asked me to describe her and all I could do was illustrate her height. I went and got a photo of her from the mantel and showed it to them. "Does she still look like this?"
"What do you mean? That's her. That's a picture of her."
"It looks like it was taken in the sixties."
I was very baffled as to why that mattered. "Is her hair still this color?" They turned the photo to show me.
"I'm not sure."
"What do you mean? You said you saw her this morning!"
I shrugged. I could not tell them if she had curly hair or straight hair, red hair or blonde hair, if she wore glasses, earrings, or a necklace, if she had any missing teeth, or what color her eyes were. That was 45 years ago and I still cannot tell you the answers to any of those questions. I'd have difficulty answering those questions about anybody, even people I've known decades.
Just then, my mother walked in the door. Before leaving, the cops chided her for raising a kid who played practical jokes on the police.
A few years ago a woman I fancied and knew quite well asked if she'd ever introduced me to her cousin. I said I wasn't sure. She pulled out her phone to show me a picture. As I watched, she flipped through her photos looking for one as I watched. She briefly paused to consider one. I took a good look at it and said, "I've never seen that person before in my life." She looked to see if I was joking. "Seriously. Never," I said.
"Lincoln, that's me two years ago."
