Back in the 90s, about 20 friends and I did something roughly similar in a house. We sealed off all windows with aluminum foil, unscrewed every lightbulb, and covered every electronic display panel. The fridge was loaded with random sandwiches (actually random, since you couldn't read labels). One small room with an exterior door was turned into a light-lock so we could order pizza. The experiment lasted a whole weekend.<p>The activities were basically long discussions, music/audiobooks/plays (before siri/assistant, so physical CDs - again random), psychedelics, and making out with your friends. I can't say I achieved any deep insights, but 20-something me thought it was pretty fun.
