my over imaginative brain

So no one knows that everyone is thinking or seeing and that has always boggled my brain. I have thought up crazy theory about what others are thinking and seeing my two personal favourites are:

1. For example the grass is green and the sky is blue right? but what if in my world the conventional colours of everything is different to someone else however they only see and hear an read what to them in the right colour but my brain didn't limit it to colour but also what everything looks like and how everyone speak so basically you would be in the same situation but seeing different to things that I am.

2. My second is theory that not everyone s in the same time. So you know when you sleep and wake up it feels so quick right so what if I went to sleep before you and I'm already awake your there with me but not your actually self because you're still asleep so as if subconsciously your not there because you went to sleep later then me and still haven't woke up however you can catch up with me by sleeping before me. This one is more of a probably never going to happen because of space time continuum where technically everything and everyone is at the same time (I may have made that up)

Just a thought.
