That was my first deep thought I remember having. I was like 9 or 10 and I asked my friend if she ever wondered if colors and sounds are seen or heard differently. Like, I see something as green so I say "thats green." But someone else might see red, and hear me say "thats red" instead of "thats green", so they say "yeah, thats red" but I hear "yeah, thats green" and then we both are in agreement of the color, even though its different to both of us. She didnt really understand what I was talking about.

But anyway, I would bet my little theory is probably 100% not the case, but its fun to think about.
