From one of the dominant theories of a material view indeed an emergent behavior from an incredibly complex neural automata.

But from our daily experiences actually reality is an emergent property from our consciousness (or awareness).

What we do feel, smell, hear, forms into concept, meaning, experiences forms our "reality".

There might be a theoretical other "reality" or it might be a bit different many think it is now, but it doesn't make it more or less real, in the sense of actual experience it's less real.
