Small, black, round bugs in my room!?

I know for a fact that they are not bed bugs. They look nothing like them and they dont bite. I'll find them on my pillow sometimes and sometimes on my carpet. My room is very clean so their not being attracted by garbage or anything, they just come in from somewhere. They are round and all black. They are very small and sometimes look like a tiny peice of lint. I cant tell if they have wings or not but I usually find them in fabric areas. Please dont say they are bed bugs because I know they are not.
