Hand a similar thing happen to me.
Three weeks before my wedding I had a job interview. I brought flip-flops to change into afterwards for more comfortable walking but was so excited after the interview I didnt change my shoes. Was walking down the stairs to the subway when I had this feeling that I was going to fall down the stairs.
Low and behold a few seconds later I went tumbling down until I reached the landing (probably about 10 stairs). I had grabbed the metal and railing to slow my fall, but the way I caught it made my lurch side ways where I hit my face on the metal rail at the landing.
Thankfully, no broken teeth or bones, just a split lip that healed in time for my wedding day!
If I hadn't had that feeling that I was going to fall, I wouldn't have reached for the railing and it could have been much worse!
