Sometimes, inexplicably ghostly encounters happen that creep you out and stick with you for life.
For example, every night in my childhood home I saw a mysterious, spectral child at the end of the hall. It would almost paralyze me with fear, and later in life I learned my parents had seen it, too.
So what's your spooky tale? Maybe you were closing your window one night before bed when you noticed the silhouette of a woman facing you. But when you tried to point them out to your roommate, they couldn't see her.
Perhaps you took a ghost tour in an abandoned building, and when you looked back at your photos you came across several bone-chilling images.
Or maybe you were watching TV alone one night when you suddenly felt a tap on your shoulder and warmth around your stomach, right where a child would stand if they were hugging you.
Sometimes getting these terrifying stories off your chest can be cathartic. So tell us, what's your own real-life ghost story?
