The Hand "nighmares My Son Steven Has"

Dreams i have had Since i was very young Wake me up Make me run Up in the corner above my bed The hand of who ever goes for my head I shout aloud and waken the house Where all around its as quiet as a mouse My parents and siblings awaken too They panic wondering what to do I easily get back to sleep As all the rest are still on their feet Next day i am told, it happened again Is it a dream or am i going insane What it is i don't understand Is it reality or is it really a hand
