I don't think so. They just "are." She sees people having shapes kind of like we see hair color. I remember when I was going to meet her first grade teacher my daughter told me, "She's a circle." I assumed she meant the woman was plump. After I'd met this slim, slight woman, I came home and had one of the conversations that over time I came to recognize:
"Honey, Ms. S isn't fat. I thought you told me she was round."
"No, she's not round. She's a circle. It's her shape."
"But she's thin."
"No, her SHAPE."
Pause.
"What shape am I?"
"Silly, you're a triangle, Mommy."
Eventually there were enough of these odd conversations that I was able to put it all together, and after doing some research discovered the phenomenon had a name. As I said, it hasn't really affected anything, although I do know my daughter finds it rather embarrassing now, and does NOT mention these things to people until she gets to know them really well.
Picasso, perhaps? He used some pretty interesting shapes in his portraits of people...
You probably have, at some level.
For example, have you ever experienced the "texture" of a musical piece?
Or perhaps you've done a math or logic proof and seen the problem laid out in "spatial" form, or perhaps different approaches to the problem have a different color or texture to them.
