I can remember things from long ago quite clearly, but like you, I tend to remember in pictures - I have mild dislexia and this causes me problems with really simple things like times tables, the alphabet and people's names! Despite doing well in most things at school - including Maths, I really struggle if someone asks me what 6 X 7 is and it takes me ages to look things up in the telephone book. I will usually remember whether someones name begins with a curly or straight letter, but that is about it! I think that we all take things in differently - if I need to remember something for an exam or whatever, I need to write it down so that I can visualise it on the paper.
