Our mind is capable of producing these things that we call cognitive biases, which shape reality to look a particular way. When I look at the world and I see red, it's unclear to me whether that red is real, right? It's a wavelength of light. And my mind interprets it as red, right? That's what I think it is. So in general, like our mind is between us and reality. Maybe I'm wrong there. But then the question still remains: Is there something really out there that you can't imagine? Right, that's the main question; generally speaking, I'm not sure how else to describe it.
