I used to do this when i was younger..

I'm 100% sure this wasn't normal. But was wondering if there was anyone else out there who did this as well.. So i remember when i was little, i used to bite my fingernails and i would chew on the pieces i bit off. And one day i don't know how i got the idea of doing this, but i took the piece i chewed off and stuck it into my eye.. the corner of the eye closest to the nose. Well they disappeared and i would never see them again, but i did this for over a year. I remember one day while doing it, I randomly freaking out because i realized what i was doing wasn't normal and could be dangerous and i stopped. But now that i'm a lot older i was wondering if that could be a problem. Like should i go to a doctor and tell them to check my eyes? I haven't had any problems with them but i feel like those nails could still be in my body..
btw has anyone else ever done this? LOL
