You, or your character, is spending their winter break with their friends and/or family in a big, luxurious cabin. Though the inside it is nice and cozy, the wind is strong and the snow is quite heavy. Last night, you heard a sound, saw something out your window, sensed something supernaturally, etc., that makes you think something bad is out there and may threaten you or your friends. 

Do you tell your friends/family?

Do they believe you when you tell them?

Is the threat real or just your imagination?

These are just a few ideas.

This story can be in either third, second, or first person.

Most importantly, have fun!
