This is just a simple plugin that will give a player a nightmare.

How it works:
When a player sleep, there will be a low chance that they will experience a nightmare and be teleported somewhere. By default it is set to nether but it can be configured in config.yml

The only way to escape this is by dying or by exiting the current world dimension.

So far there is not much in this plugin aside from teleporting them to a random location. But there's an option where you can set their Gamemode to adventure when they teleported, therefore they won't be able to place/break blocks until they exit or until they die.

NOTE:

• If you set the nightmare world to your overworld dimension, then you can only escape by going to Nether or End or by dying.
