It's a real bug. Do not squeeze it. Turn off the screen an put a bright light next to the side for a night. Maybe you will be lucky and the bug will go away to the light. I wasn't so lucky and the bug died between layers of my screen. Now I have line of about 5px that are black. Saw this issue on other people monitors too, especially when you are a person that likes to work in the dark, during the night with window opened. Bugs are attracted by light and warmth of the monitor and just crawls in to it.
