I’ve been seeing them since last November. They just crawl around and when I look at them properly, they vanish.
Today I’ve had quite a few on the ceiling, one coming from underneath the door and one on the pillow next to me but when I search for them I don’t find anything.
It’s so annoying because sometimes when I see one on my bed, I freak out and throw all of the sheets off to see where it has ran to but nothing is there!
