What are these little white (sort of tan) bugs in my room?

i found four of these tiny bugs crawling on my ipod dock so i got scared and went to change my sheets. i pulled up my sheet and there were two more under it (they were on the mattress pad). my ipod thing is right by my bed so i think i might have an infestation somewhere. they sort of look like the bugs you find in books but they're a tiny bit bigger and i don't have books near my bed. i'm not sure if they're dust mites because i don't think you can see dust mites without a microscope. i don't have any bites, either.
