Sorry Spock, yeah I did kind of cherry pick in your argument and I know essentially what you mean with all that you said. So you did a good at trying to clearifying your reality, and our assumed shared reality. But thing is that when we try to talk about things that we simply cant percieve here/now. Then it is more of a dream than anything else. I cant for example say or do something to you and expect an certain outcome from you. And even if Im 100% sure about what you might say or do in "theory"=thought. That certainty will not be more real than a dream, even if the outcome matches the expected outcome.

To sum it up some: thought=beliefe= Dream. So actual reality=dream.

This does of course not mean that we can't handle the different state of dreams just because we live in them. Reality might feel dense, but that doesn't make it less of a dream.
I repeat again: actual reality =/= what you see as reality
Im almost with you on this. But since seeing does not always mean believing. I would say ("actual" reality = what you believe). So there cant be any other reality than the one you are in yourself.
Why do we assume that something must be real to us in order to be real at all?
We assume that because we make up our own reality. So if I say that the earth is flat. Then that doesn't mean that it is real unless you believe it to be.
