The bed is brown, like maggots.

Bed lice. The brown maggot-shaped small meat bugs on the bed are bedbugs, which are distributed all over the world and mainly inhabit the four corners of bedsteads, brown curtains, curtains, walls, ceilings, tables and chairs, bookshelves, books, bedding and clothes, and behind wallpaper. The reason of bedbugs is that long-term dampness of quilt cover will breed lice, and irregular cleaning of quilt cover or bed seam may lead to lice reproduction and skin damage.
