So, I have some sort of parasite living in my bed. I have bites over every square inch of my body, and it is terribly painful (o hai itchy buttcrack) and obnoxious, especially when trying to study. Whatever this creature is, I have seen several of them; they look just like specks of dirt, except moving. I'm pretty sure bedbugs are bigger. What are these? How can I get rid of them? ETA: I am pretty sure they're not bedbugs. They are a sandy-brown color, the size of chiggers.
