I have a childhood brain injury that affects my working memory and sequencing ability, among other things. I think in pictures with a verbal commentary, although words disappear soon after I think them. My brain stores information everywhere it can fit: in emotions, music, patterns, movement, etc. Interpreting reality is fraught with error. You describe the effect very well.

I am working on a personal knowledge system to compensate. What are your ideas on this subject?

Popular PKS systems expect the user to adapt to "the system," rather than adapting to the user's particular set of needs. I consider each user to be a unique combination of common components.
