As a matter of fact I DO have a out of breath story.
The one time that sticks in my mind was I was sleeping, and I don't know if I inhaled some saliva or what, but I woke up gasping. I couldn't breathe in, only out. I couldn't speak to wake up my husband. It was very scary. I started panicking which only made it worse.
Finally my husband heard me gasping and woke up, looked at me, and smacked me hard on the back. Its like it jump started my breathing again. Then I caught my breath and went back to sleep. It was the longest 30 seconds of my life!
I don't know what happened. It's never happened before or since then. Terrible feeling.
