The mind is necessarily a function, it's performing its function over a vast array of inputs (memories, senses, etc.) and making sense of it as it goes, and it doesn't exist without energy expenditure to keep computing itself.

To me psychedelic experiences break through the inputs, they become fuzzy and integrate in ways they aren't supposed to in normal functioning, it's why we feel a different sense of connection to anything else, filtering in different ways inputs from our senses and experiences, including the sense of one's self dissolving.
