Yes, same thing. I wouldn't be able to draw them, not even explain them, but sounds produce images in my mind. Colors, patterns and movement. All different for each sounds, always the same for the same sound.
I've been thinking for 5 minutes trying to find some kind of explanation, and i did think about it many times in the past, but no, i am not able to explain what i see, i just see it.
I've never been able to put on paper what i see in my head anyway....
