It's anxiety/OCD, I've suffered from hundreds of obsessions and some of them were the same as your daughter's right now, it's actually the reason why I'm up right now past 3 am. For some reason, maybe about 4 to 8 times a month (sometimes more), I'll wake up in the middle of night in panic thinking I'm chocking on needles, clothes pins, marbles, paper, etc. and I literally run out of my bedroom flipping out and running to my mom's bedroom crying for help and trying to cough or throw it up, until I actually wake up enough to realize that I'm fine (which happened tonight, though I don't run into my mom's bedroom anymore, I run to a bathroom instead). I've also had this intense fear of swallowing objects at some points growing up as teenager (because of OCD) where I was terrified of picking up coins and pens etc, because I thought I was going to swallowing them. The only thing I can say that helps is to lower the overall anxiety with the help of a professional and to learn how to treat OCD's symptoms with ERP therapy if this is the case. It's actually a good thing that you've noticed these things when your daughter's still young. Believe me, OCD/anxiety left untreated for years, can destroy someone's life. Take care!
