Red dots on face?

Em

Anybody know what these might be? I’m assuming some sort of bite but he isn’t scratching at them at all and they are flat. Don’t look like a bite, moreso like a busted blood vessel. This is the second time he’s woken up with them. The last time he woke up with one on his ear, one on his cheek, and one on his head. They faded after about 3 days.
