<human>: So, I live in an apartment with three roommates. I moved in at the beginning of January, and since moving in I have received dozens of strange bug bites while I sleep. However, in attempting to identify the culprits, I have been unsuccessful. Here's the situation:

* No one else in my apartment has gotten any bites. My roommates and I regularly cuddle and there has been no cross-contamination.
* I was treated for scabies and took the necessary preventative measures to stop a relapse, but this was ineffective.
* I switched out my mattress and my bed frame for completely new ones and have washed my sheets and blankets several times.
* I have checked around the room for signs of bugs, but nothing has proved fruitful. I have seen no spiders, fleas, or mosquitos in all my time here.
* I had a service come in and check for bed-bugs, and they couldn't find any. 
* When I visited my family for a week at home, I didn't receive any new bites, so whatever it is is definitely in the room.
* Most of my bites appear on my arms and hands, if that is helpful...? Some on my feet and back as well. 

So, what remains is this: Some sort of bug that is living in the room and does not spread easily. Advice? Similar stories? I'm getting pretty desperate here: I'm really tired of being itchy.
