What's the most scariest experienced you had?

When i was just a little kid, I feel asleep with my bedroom door open - my mum must of forgotten to close the back door, we have a screen door and a wooden backdoor that closes over the screen door. I woke up to a terrifying noise, i couldn't make out what it was. I couldn't move and didn't even want to breathe. I'm not sure if it was sleep paralysis, It was the only time in my life where I experienced something so terrifying. That was the most scariest experience I've had so far in life.
