The nature of consciousness is still a subject of ongoing scientific investigation and philosophical debate. While there are various theories about consciousness, the idea that consciousness is a field and the brain acts as an instrument that interacts with this field is not a widely accepted or mainstream view within the scientific community.
Most contemporary scientific theories of consciousness focus on understanding how subjective experiences arise from the physical processes in the brain. These theories generally consider consciousness to be an emergent property of complex neural activity, involving the interactions of different brain regions and networks.
Some theories propose that specific patterns of neural activity give rise to subjective experiences, while others suggest that consciousness is an integrated process that arises from the global activity of the brain. These theories typically do not invoke the idea of a separate "consciousness field" beyond the physical brain.
That being said, consciousness is a complex phenomenon, and our understanding of it is still evolving. As scientific research progresses, new theories and perspectives may emerge. However, at present, the hypothesis that consciousness is a field and the brain merely interacts with it is not widely supported by empirical evidence or the scientific consensus.
