Sounds like something I did not too long ago but it was in my sleep!
I dreamt that I picked something up and swallowed it then woke up in a panic. I had swallowed something and had the strangest thing going through my head that it was a twistie tie :LOL Then I woke up a bit more and realized it was probably one of those plastic hang tags from clothes; I had bought my son some shirts that day and took the tags off on my bed. One or two were probably leftover. I never did see it or anything, but believe me I tried to make myself throw up; I was mortified and amazed all at the same time. Now I make sure I don't have anything I can swallow near me!!!!
