A childhood belief about around the house

When I was a lot younger,a particular picture of my Great Grandma sat on my Mothers dresser.When I would walk in the room it would scare me so bad as I thought she was watching me from the picture,she had passed away many years before I was born.You couldn't convince me in any way that she wasn't going to come and walk towards me out of the picture.So in my young mind I thought if I laid the picture down on its glass that Grandma Stevens was trapped under the glass,and so for years my Mother had to set this picture back upright and never knew I was the culprit.I always wondered what my Mother thought about the mysterious picture lying face down,but I never asked her.
