The Grave Keeper

You have been hired to manage a graveyard in the mountains for 10 days. The company that hired you says you're supposed to take care of one task each day, working during the day for three days and then at night for the next three days. And if you notice anything out of the ordinary, you are to return to your quarters immediately and report it to the company by phone. After reporting the anomaly, you're told you can go to sleep without doing any work. But be careful, you shouldn't call the company if nothing unusual happened. Beware, if you fall asleep without finishing your work or reporting anomalies, you'll be stuck with a day that never ends.
