Bugs In The Bed

I don't know what they are, but I have bugs in my bed.

I checked Wikipedia, and they seem to be too small, and they look different, than bedbugs.

Nevertheless, they kind of creep me out anyway. They don't seem to bite, but they sit on, and irritate, the skin when I'm not looking.

I wonder where they are coming from, and what their mysterious appearance means?

I mean, I do shower, and stuff....
