umm no. the 'witnesses' are kin to the 'watchers' of heaven but is this merely a reality going on inside of someone? nay i say nay. at least not in the superficial sense of understanding what "inside" a person even means. you see in heaven we probe deeper and deeper. the outer layers reveal a mass of angels, countless. then the 24 elders then the 4 living beast then the lamb slain from before the foundation of the world. ahhh but such is hard to understand. so that is what reality is.
look man it is not about a mere brain memory manner of things though that is part of it. if this what we exist as is all we have then you would have to be insane to desire to exist forever as a fallen creature. how boring this world is, the higher parts of life are supposed to give birth to the things of this life that we might play in.
what gives life to a thing? the difference in between going to church to worship because you love God and because you are commanded to "not forsake the gathering together" is huge. one obeys out of love and the other obeys, possibly out of authoritarianism. now now i'm not saying that is all there is to such an abstract thought about what could occur in reality. each happening is it's own thing. I merely speak about specific possible things that could be occurring with a person. it could be that such a person has faith in God and so he obeys the "do not forsake the gathering together", he might have fear, but he is doing it because he thinks it is right. the angels are pleased with that, surly they are pleased.
but you have to understand that salvation is not of gain, that is why the merchants weep over the destruction of babylon. rewards in heaven are not like they are in the earth for our brothers are our crown and joy, and who do we cast our crowns to but Jesus and we know all things are delivered to the Father.
how sad, how sad that you would say "the Father" rather than "my Father"
