I am currently reading Girl, Interrupted by Susanna Kaysen, and in one of the chapters she says -
"I was having a problem with patterns. Oriental rugs, tile floors, printed curtains, things like that. Supermarkets were especially bad, because of the long, hypnotic checkerboard aisles. When I looked at these things, I saw other things within them. That sounds as though I was hallucinating, and I wasn't. I knew I was looking at a floor or a curtain. But all patterns seemed to contain potential representations, which in a dizzying array would flicker briefly to life..."
One of the criteria for borderline personality disorder is severe dissociative symptoms, but would this be considered dissociative? I can't manage to find a clear answer online. If it is not, then what explains what is happening to her?
Thank you in advance.
