I moved into a new place. The owner took a blanket from a cupboard I think this was most likely the source of the insect. I woke up with itchy feeling on my body and particularly hair. I saw dead bugs in the bed. It's not great quality photo but can anyone tell me what these might be or narrow it down. Bed bug? Fleas? Termite? I'm in Algarve Portugal. They were dark brown or black. Please help me!

Hi,
Details are not obvious but the shape doesn't look like bedbugs, termites, or fleas to me.
There are some bugs that can eat fibers, maybe that, and your itching is coincidental.

Maybe carpet beetles
