I just recently came across an article about Aphantasia and i’m still not certain if I have it, but I always assumed the way my imagination works is normal. When I picture things I don’t see pictures, instead I see the back of my eyelids but I think about the concepts of things. For example, if you asked me to visualize a rose I could imagine the concept of the shape in my mind, and almost pull the color forward but I can’t actually see a clear picture of a rose, whereas in dreams (when I have them) I usually have a very vivid and immersive world created, which is why I kind of understand that my daytime imagination might not be normal. As far as mentally walking through my house its similar I guess, I can do it mainly because I probably know my house well, I kind of visual the shape of my walk and the shapes of furniture and place loci on them, and when dealing with loci in my memory palace I have the concept of what they are and that’s what makes me remember them rather than a vivid visual picture of them. This usually works ok for me, the much harder part for me is remembering enough locations vividly enough to have enough places to put loci.
I always thought only savants could have those magnificent memory palaces, perhaps now I realize instead, I am the exception, rather than the norm. So I think I might be doomed as far as a successful memory palace is confirmed.
But I am curious what everyone’s thoughts are on this, if you have any kind of experience you would like to share, or advice, that would be appreciated!
P.S. This is Aphantasia for those who don’t know
