What is the name of this movie?

I think it was a horror movie because it was scary to me(i saw this film about 10 years ago). In this movie the central figure was a woman. I remember one scene where the woman was in house and some kind of a slime monster attacked her from washbasin. And there was i think a hand that moved and also attacked this woman. If I remember right then the woman kill' d that hand with a knife. Please help me and tell what movie this is, thank you!
