I've updated a post on my personal blog about having aphantasia — the inability to visualize things in your "mind's eye." I added some thoughts that people with the condition posted in a Facebook group about aphantasia. Some believe it to be a curse, because they can't visualize the faces of loved ones etc. Others see it as a blessing, because they can't visualize traumatic events: https://mathewingram.com/work/index.php/2020/04/05/aphantasia-when-you-try-to-picture-something-in-your-mind-and-nothing-happens/
