As far as we know (we currently cannot prove or disprove panpsychism) that is true. However, I think it is important to keep in mind that we do not perceive reality as it is. Rather we experience the brain's interpretation of reality. So in that sense, human "reality" is basically what most of humanity agrees that it is.

I think it is both. The individual realities of living beings adds a layer on top of the actual physical universe.

Our priors shape how we perceive the things around us.
