Has anyone ever had this kind of dream?

I had a dream about this "creature" that had a long black body. the body was not solid. The face was round and very whit. it didn't have any features on its face except for silver illuminating eyes. It came out of the water and had an evil presence. this creature soon changed its appearance, but i cant remember what it looked like. oh ya, and there were 3 of them, not just one.
