Well how do you know you're actually living in it?
Because I do. There's not a good enough argument that what I'm living in isn't reality, so I don't consider anything except the likely to be true.
Can you actually prove that everything you see is real?
I don't really have to, if you don't believe that anything you see is real then that's your problem, not mine.
You can say that because you see stuff and feel comfortable with your own decisions you're in control, but can that really be proven?
Again, you talk about proof like I need to prove anything to you. I don't feel that's necessary because I don't need your validation in order to continue living in reality.
