Hi Matthew I understand how you feel as I also have aphantasia and also SDAM which is severely diminished autobiographical memory and interesting enough I also have a very strange mild form of synesthesia in that I see time. I see seasons as a bar graph. I once asked a friend ” what do you think of if I talk about the season Fall and they started describing the trees changing colour and all the other things that are associated with fall. I said yeah but can you see September can you see October and they kind of looked at me and said “you have synesthesia”. so to me the months of the year are a bar graph. it’s useless I mean what are you do with that? but I thought I’d remind you that you’re not alone. 2% of the population has aphantasia and severely diminished autobiographical memory. there’s also a Facebook group for folk with the condition. some people are fine with the condition; other people are really pissed off about it. feel free to reach out if you ever want to chat more. Martha Hendricks sent me your blog by the way.
