Do we all see the same?

This may be a weird thing to think about, but do you think that we all see and hear the same things?

Like, what if when I see something blue, you see it green. Or to you, an apple is pink, but to me it is red.
And if we see differently we must hear things differently. Because i we didn't than we would've discovered that everyone sees things differently. So when we were in preschool and we learned colours, everyone would have seen a different colour for the same object, but we would all think that we were seeing the same thing. If we were talking, and you told me that your room is going to me a raspberry colour, I might hear you say yellow, or green. I would even see you lips move to form those words, but your would've heard you say raspberry. I'm not sure if you understand what I'm trying to explain.

It's a pretty perplexing thought.
