I find this interesting because, personally, I am very poor at mental imagery.
I have a poor memory for details, including names and faces of people. It's not uncommon for someone to greet me by name, and I will not only not know their name, I very well might not even remember having met them before. In reading a book, often I loose essentially all recollection of the text just a few pages back. Such is also often the case, for message strings at .
With maybe very rare exceptions, I can not form visual images in my "minds eye". For example, I can stare intently at my pet cat. Then, when I close my eyes, the best image I can form it along the lines of a severely underexposed photograph. In general, it seems that the best longer term image recollections I can do, are more along the lines of being geometric discriptions.
When I wake up in the morning, it is relatively rare that I have any perception of having dreamed. Any dream visual imagery that I do recall, is vague and often rather abstract. What little imagery I do recall, is a foggy black and white.
I am curious about how others are, relative to me.
