Where is the consciousness located? Cosmic Consciousness?

I recently became aware of questions regarding the location of consciousness. The argument put forward is that the consciousness is separate to the body. This is not something I considered before. The first is conjecture by a Doctor Fenwick https://www.psychologytoday.com/intl/blog/think-well/201906/does-consciousness-exist-outside-the-brain "Hence, in Fenwick’s view, the brain does not create or produce consciousness; rather, it filters it. As odd as this idea might seem at first, there are some analogies that bring the concept into sharper focus. For example, the eye filters and interprets only a very small sliver of the electromagnetic spectrum and the ear registers only a narrow range of sonic frequencies. Similarly, according to Fenwick, the brain filters and perceives only a tiny part of the cosmos’ intrinsic “consciousness.” Fenwick is not a physicist, so I dredged the following link, the mind of wigners friend which supports the Fenwicks theory. The second is based on quantum mechanics https://www.jstor.org/stable/23040667?read-now=1&seq=1 The key points central to the article are "A. My body with its internal nervous system(explored to any future degree of physiological completeness) functions as a pure mechanism according to the laws of nature. Further more quantum mechanics is the ultimate basis of the mechanism. B. I am aware that by incontrovertible direct evidence of knowledge (information) entering my consciousness." The 3rd is offered as evidence of the first 2 links https://youtu.be/Uq8l4XVfgPA Am I correct in thinking if all the information in the universe exists in a timeless dimension(membrane) of space and our brains only access a part of it, making us who we are. Can we access more information towards enlightenment maybe? or sixth senses? via meditation a bit like the Buddha may have done? In particular can any one point out if there are any errors in the second link that might make its central argument incorrect?
