I believe space-time is a field in which people are embedded. It is a field with entropy becoming disorganized and that is what is regarded as time.
Incidentally it could be that If the primary fields of the Universe are finite in substance and all are stretching in expansion with entropy disassociating them that could be a reason for the apparent expansion of space time as the fields themselves add gaps within themselves.
Mass happens to be entangled fermion-built entities experiencing entropy while bosons as massless particles in fields experience it less or not at all.
I have walked a fair amount in near total darkness in a forest with sharp dead lower branches sticking out all around. One keeps one's hand out in front to protect the eyes yet sweep for a path through. One can do that with eyes closed; it is all entirely conscious choices without subconsciousness playing a significant role. The subconscious and consciousness are all part of the phenomenon of mind arising from the brain though. Those synapses and neurons are part of one system that consciousness is the awareness of.
