I weaken all men for hours each day. I show you strange visions while you are away. I take you by night, by day take you back, None suffer to have me, but do from my lack. What am I?

Why this works

This riddle cleverly describes the nature of sleep through a series of intriguing lines. The first two lines highlight how sleep can leave people feeling drained or weakened ("I weaken all men for hours each day") while also suggesting that dreams—often bizarre or strange—occur during this time ("I show you strange visions while you are away"). The next lines illustrate the cyclical nature of sleep, emphasizing that it takes you away at night and returns you to consciousness during the day. Finally, the last line reveals a profound truth: while no one wants to be deprived of sleep, many suffer from lack of it, making sleep an essential, yet often overlooked, part of life.
