"This incident took place around 20 years ago in Lincolnshire, England, where I live," writes Helen. "A friend of mine, who lived some miles away, came to stay for the weekend with her kids.

Later in the day, I went upstairs to put something in the bedroom and found that I couldn't open the door...." Why? You'll have to read the rest of Helen's peculiar story to find out.
