Thanks for your reply Laurie. It really is interesting as you say - I keep asking my partner questions like "can you really see the scenes in a book while you're reading it?" It certainly helps to explain why she and I have very different memories of things we've experienced together. I am becoming more confident that my aphantasia is acquired. I spoke to my mother about a visualisation exercise she used to help me with when I had my cancer and she confirmed that I appeared to be seeing the images as required. One thing I definitely do remember is the first examination after I returned to University when I recovered. I sat down and suddenly realised my mind was completely blank I couldn't recall any of the things I'd learned. At the time I thought it was exam nerves but now I wonder if it was the first sign of anasphasia! One thing that does puzzle me is why I didn't notice what had happened at the time. Do you mind me asking how you worked it out when it happened to you?
