In the spirit of Halloween - Paranormal or not, what is the scariest, creepiest or most unsettling experience of your life?

Maybe doppelganger or glitch in the matrix but this spooked my spaghetti for a while. One evening, my mom was taking a nap after work upstairs and I was downstairs in the living room playing some video games on the television. Suddenly I heard my mom's voice saying "Come here coyotes" and so I started walking upstairs thinking she needed me to bring her something. Then I heard her voice beneath me saying "No, downstairs!"

I walked down back to the living room and looked around. I didn't see my Mom and thought she was playing a creepy joke but it was December, Halloween was a while ago but still, I know my Mom might have just wanted to mess with me. After all, I no longer heard her snoring from upstairs so she probably stuck downstairs. I turned and looked down the hallway and saw the basement door ajar and my Mom's head poking out looking straight at me.

"What is it?"

"Come here!"

"Yeah, but what do you need?"

"Just come downstairs, I need to show you something."

Now I was a bit of a wuss when I was 9 years old (when this happened) and I didn't watch horror movies, I should have known that following my Mom downstairs would have lead to me being killed off. I walked cautiously towards the basement door and I was about 5 feet from my mom and her head shot quickly backwards behind the door. I didn't hear any footsteps and I pulled the door open and stood at the top of the stairs looking down into the dark basement. The light switch was at the bottom of the stairs so I was fucked six ways till Sunday. I saw a figure moving in the darkness away from me in the basement and began walking down two steps when I heard my mom's voice again but it was more high pitched saying "Come down here!" and suddenly I heard what sounded like a loud bear growl from upstairs. I instantly recognized it as my Mom snoring and bolted up the two steps and slammed the door to the basement and rushed up to my mom's room where she was asleep. It took me a bit to wake her up since she was a heavy sleeper but I explained to her what happened. She's interested in ghosts and such and got really scared.
