You found the Quiet Easter Egg

Someone doodled on a coaster, which must have fallen under the seat. It reads:

1. I’m the reason your video won’t end,
   forever replaying again and again.
   
   
2. I rise and fall both night and day,
   pulled by the moon in gentle sway.
   
   
3. From east to west sun's journey flows,
   but how often does the horizon glow?
