What is biting me in my sleep?

I live in the southeast US. The last week or so I wake up each morning with a few large, raised itchy bumps, usually on my torso or upper arms. The bumps have a small yellowish pus-filled center and are obviously some kind of insect bite. I never feel myself being bitten. I am also feeling find otherwise, no symptoms of any illness.

I thought at first they might be tick bites since I work outdoors and am in the woods alot, but there is never a tick attached in the morning when I discover the bites. However, I have found quite a few ticks on my dogs lately…

Anyone have any idea what is biting me, and how I can get rid of the critters?

Bed Bugs ?

Why oh why oh why did I click? I will never sleep again.
