Actually the dimensionless point or singularity vis a vis the Big Bang, is an imaginary point from which the first moment of dimensionless reality came into being, one Planck length-time "later". But science has settled on using the terms local and non-local space for our 4-D universe and timeless and dimensionless quantumland, respectively, because, once you define it that way, things become more intuitive.
To me, consciousness seems like what the brain produces when neurons trigger and interact "externally" to our universe in that timeless, distanceless quantumland. But I'm on shaky ground there since biology is one of my weak suits. Our brains could well be like the universe that spawned them, individual biological self-contained quantum computers in a giant non-biological quantum computer.
