Is it normal to sleep with a light on?
Yep.Totally normal
Yes, it’s normal to sleep with a light on. Plenty of people find a little light comforting or simply prefer it that way.
Some people feel more relaxed with a light on, especially if darkness makes them uneasy, or if they need to get up during the night. Others are used to it from childhood or share a room with someone who likes a night-light. There’s no one right way to sleep.
