I discovered that I am a complete Aphant when I was 60. My daughter was describing a dream in great detail - I said wow sounds like you dream in HD and she replied yes, why don't you? From there came teh realisation that I don't see pictures at all. Yet I am an engineer and I 'see' flow charts, diagrams, mindmaps - I create good ones too on paper/electronically. But I realise I don't see them at all - I just have a good relationship mapping capability - I know where everything else is in relation to everything else I think - I store metadata I assume and then build what I need to from that.I can picture rooms in my house and rooms for years ago - but not as pictures, more as concepts with the details in them, the bed over there, cupboard there, etc - no colours, no drawings, just relationships.I did a two year world tour 17 years ago and I am remembering elements now - teh wide open vistas of Africa, the ball court of a Mayan temple - I can remember them, but again I think it is relationships - it certainly isn't the actual pictures in my photographs.I do think this has been a super power for me - looking back. I have often created new systems, concepts in my career that come from ;nowhere' - that far exceed what my colleagues and staff have been thinking. I think this is because they are constrained by teh diagrams they have before them - teh system maps, the architectures, etc. Whereas with no pictures, just metadata/relationships, I naturally roam wider, can 'see' (feel?) relationships that aren't already there, that maybe would be prohibited by the existing diagrams (sort of round teh back or connecting left and right edges or just off the map altogether). It is hard to describe this all as it is of course natural for me and I am having to describe it unnaturally.What I find most interesting is that for years I would describe my thoughts visually "I see this being connected to this there", etc - adopting teh natural language of others because I must have assumed everyone was teh same as me, rather than realising I was teh outlier, and using 'see' mentally meant a whole different thing!
