Villagers Can Sleep In The Nether, And The End??

Normally, players can not sleep in the nether or the end, because it can explode.

 

But villagers can sleep in the nether or the end?? That is dangerous.

 

1. Create a world and be in creative.

2. Find a nether or end portal, or just build it.

3. Once you are in the nether or the end, spawn a villager, and get a bed.

4. Set the day to night.
