Them and they are OK as long as the person is unspecified. Especially in reference to an unknown gender. "Him or her" becomes replaced by "them" until the sex is identified. "Him or her" is the formal and best way to say it. "They" is informal and frowned on by english teachers but is used often in common speach.
You do use the forms of they a little too often in this poem though, when in some places you could omit it entirely and still make the point. Or you could just change "Someone creeps" to "They creep" all though that would give you another they. Ah hell. just change the title to "Them" too. I liked the story though.
