First and Second Sleep is something that our ancestors thought normal.
Europeans who lived in the Middle Ages practiced what we now call biphasic sleep. The first sleep started at sunset and lasted until about midnight; then people would wake up and stay awake for 2-3 hours. Some used that time to pray or read, and some spent it with their family or neighbors. Then came the time of the second sleep, which lasted until sunrise.
