Snake in my room

Question
I have found 4 all black and about about 4 to 6 inch snake (im guessing) in my room and living room on seperat occassions. I am not sure what kind of snake it is if a snake at all. It moves quit quickly and also moves its body like a snake. Any advice and also do you know what kind of snake it is.. it has no distinct markings or colors other than black. It also seems to be able to swim(as I tried flushing the last one)
Thanks!!!
