Some folks don’t need to watch horror movies to be afraid; they’ve experienced terrifying experiences firsthand.

While some weird situations have simple explanations, others leave you wondering what exactly happened. The true stories we’ve collected today will linger in your mind long after you’ve finished reading.

The Story:

I awoke at 3 a.m. to obtain water. My son’s voice came from his room, asking, “Mom, can you turn off the light?” Without thinking, I turned it off.

As I returned to bed, I noticed my son was on a camping trip. I rushed into his room and froze—it was empty.

I was certain I heard his voice, or at least someone speaking in a tired tone. When I told my husband, he laughed and claimed it was probably all in my brain, but I knew what I had heard.

That moment still creeps me out.
