I was just listening to a podcast where someone said they have no mind's eye- they can't visualise things in their heads. Apparently, some people can visualise something in colour and 3d, some in colour and 2d, some in black and white 2d, some just as a hazy image and some not at all-no image at all, just words. I realise that now I can't think about which I might be....I THINK I'm 3d colour, but I don't know! You?
