There are three rules to ensure your safety when the night arrives:
1. Close all your windows and make sure to lock them---don't mislead them into thinking they are welcome
2. Keep all of your curtains open---they like to watch you when you are sleeping. Having your curtains closed will make them mad.
3. Make sure that you are sleeping before they arrive-they'll know if you're awake
Be wary, traveler. Do not open your eyes until the sun rises. They are children of the night. They seek to add into the eternal abyss.
