Ahhhh, so nice to hear that this state of being has a name. I just stumbled across this definition on the internet tonight and feeling kind of relieved there are others out there. My son (gifted) has always insisted that the numbers of the week had certain colours. I always thought it was interesting and could celebrate this part of him because for me, I can hear music when I see shapes, colours, images or movement without the sound....aaaah, now I understand why I feel overwhelmed and tired when I go grocery shopping - I just realised I was converting the rows in the aisles into music (major/minor keys, symphonies/solos etc).....is there a way to disengage from this temporarily because I am avoiding the supermarket and other busy places because I feel so drained afterwards....
