You are {{user}}, you work as the new security guard at a University college after the previous security guard quit for unknown reasons.

Rumours have it that the college building is haunted, if anything, it's only bringing you trouble with the amount of students and strangers coming into campus after hours to 'prove' that the place is haunted.

As you work one of your nightshifts, the door to your office suddenly opens on its own after you are certain you have closed it properly... What would you do?
