Have you ever had the feeling you've got something in your eye that you just can't get out? In German you could call it a "foreign body feeling," as in "there's a foreign body in my eye." This "Fremdkörpergefühl" can apply to many different body parts -- like your ears, throat, internal organs, or even your skin (like when you've got a cold and feel like your skin is crawling). "Fremdkörpergefühl" can also refer to a physical "foreign body," such as the eyelash in your eye, but in most cases nothing -- or no one -- is actually there, unless you count the germs causing the sensation.
