I keep waking up with dime-sized bites on my arms, and I don't know what they're from. They itch like a standard mosquito bite, perhaps a bit less, but they look much different. They don't resemble any bite I've ever seen, and I've compared them to photos of bed bug bites just to be sure. Even stranger, they disappear after a few hours, or a day at most. Anyone know what the hell that could be?
