Human consciousness is created with neuronal firing at multiple levels, many scientists have proposed Orchestrated Objective Reduction Theory. This theory explains that consciousness is a quantum process facilitated by microtubules in the brain’s nerve cells.
As highlighted in this article consciousness is a quantum wave that passes through the microtubules. As any Quantum wave has properties of superposition and entanglement, human consciousness can be connected and be in many places at the same time.
