This quote reminds me of Thomas Pynchon’s book Vineland, and the Thanatoids he writes about.

“If you want to know what death is like then become aware of your own consciousness as it is divorced from physical activities. You will find that it is highly active. With practice you will discover that your normal waking consciousness is highly limited, and that what you thought of once as death conditions seem more like life conditions.”
