In 1989, my aunt lived in a older house and there had been strange things that would happen there. She heard footsteps going up her staircase, both day and night, and it would happen off and on. Once, her niece stayed the night and wasn't aware of any of this! Her aunt didn't want to scare her. When her niece went to get ready for bed upstairs... she suddenly heard footsteps and they walked into another bedroom and the door closed shut! She thought it was her aunt. She asked "Is that you, aunt Nancy?". She got no response!
The next morning, she asked her aunt if she had come up the stairs around that time she was getting ready for bed. Her aunt said "No!". Her niece was a bit scared and then said "I heard footsteps... who was it?" Her aunt answered "Oh, that's old Charley walking around! He once lived here before me! And he died a few years ago." My aunt wasn't scared and just accepted it. But her niece sure was scared! She never stayed over night at her aunt's home again!
