I've got Synaesthesia relating to digits 1-9,letters,days of the week,months and countries.
I thought at one stage that with the countries there was at least a logical explanation as a
a lot of them correspond with the colours of their flags,but then I realised I see Japan as
purple,Norway as blue,Sweden as red and Russia as green.Not logical after all
