The discovery of the default mode network (DMN) and the role it plays in our perception of reality are also mentioned in "How to Change Your Mind", a recent book by Michael Pollan , which examines in great depth all the issues you mention and more. I highly recommend it to those interested in the nature of consciousness.

"How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence"
Highly recommend it.
Joe Rogan had Michael Pollan on recently, who wrote The Omnivores Dilemma and a new book How To Change Your Mind which talks about the benefits of hallucinogens. They also briefly talk about the psychotic breaks some people will experience as a result of widespread use and shrug it off like it’ll be fine. Aldous Huxley wrote a book about his use of mescaline called Doors of Perception which felt almost unintelligible and very strange to me as a person who has not (and will not, as my mental health is great but I’m certain I’m at risk of a psychotic break from hallucinogens due to family history) done psychedelics.
