Design Thriiler Novel Cover [sleepwalking]

My requirement is too specific. I am not sure who can do this job. But I give it a shot. It's the book cover of a thriller novel. The topic is sleepwalking. The tub spills out of the water and there is a knife inside. Anxious and gloomy feelings somehow and the room door is opened? What happened and who was doing that all night? It wasn't a dreamland, a real nightmare. Make 2 versions of the cover, with 1 and 2 author names.
