It seems like you have had a visual memory in the past, as it seems you know what it is you are missing. I have had it since I can recall. The struggle for me is getting others to accept I'm unable to see the world the way they do. Recalling events in the past for me as well is better than my partner that does not have Aphantasia.  I wouldn't even call it dark but an "absence of" and quiet. My meditations are refreshing; there are many forms of it, explore other types. See what is best for you. 

Hi! Have you always had aphantasia or did you get it later in life? I used to have a vivid imagination and visualization, but now its all gone for me suddenly. I Feel like i am missing a big part of my life
