One theory is that the brain is an antenna and consciousness exists outside the brain in another dimension. Consciousness is a type of magnetic field generated similarly as a signal is transmitted from a radio tower.
The question then becomes…is the brain sending or receiving? If it is receiving, then from where does the energy originate? If it is sending, then to where and to what is it sending.
I don’t know - it’s over my head :-)
It has just made intuitive sense to me that consciousness is really ‘out there’, not ‘in here’.
