I also have a less scary incident.
My grandma pulled into the parking lot and called for help with her bags (She just came in from the Bahamas). I was picked as the little schlep, so I went down to help her.
I wasn't thinking as I went down the stairs. It rained earlier, and sure enough, I was flying down the stairs. I didn't even hit any of the other stairs, I just fell down to the next floor. I was in shock while I got up and looked around. My arm was limp so I just held it up while I went back to the house (forget grandma she can help herself). As soon as I sat down on the couch the pain set in. I fractured my humerus and had to let it heal for like a month.
One time, I was having a dream, and then in the dream SOME forgetTARD MENTIONED HOLDING THEIR BREATH and then I woke up gasping for air. That was the first time I experienced sleep paralysis, I couldn't move a single thing on my body for like 10 seconds. I only happened 2 times more in a short time of the first incident, but then it hasn't happened since.
