What is this bug??? Is it dangerous

So literally I’ve had this same looking bug appear in my room and I have no clue where it’s coming from. There’s is another type of bug that is same size and looks like a lady bug this one in the pic has different shape.

One appeared on my clothes draw, laundry bag, and literally crawling on my pillow while my FACE WAS ON IT. Like wtf???

How do I get rid of them and where tf do they come from I’m so confused

I am also from UK
