Now you mention that, my scariest experience is actually Sleep paralysis. I was dreaming at some point, and for some reason I was driving in a car, and someone came up beside me and started shooting at me, I woke up and could still hear the gunshots, whilst I couldn't move or anything so I was like "Fuck were actually getting shot up, this is it, this is how I'm gonna die", couldn't move anything but my eyes, then I could again and my heart was beating like crazy as if it has stopped for 2-5 seconds.
