I had a dream I heard something evil

[B_Carter]

I had a dream a while back that I was walking down a long dark corridor with a boy that I liked. half way through the boy I'm with points out a dark figure in the hall and he is holding a knife. For some reason the boy I'm walking with attacks this guy and gets hurt real bad. We are near the exit so I grb the boy who still is trying to fight the stranger and I fling him out of the room and I turn to face the stranger. The stranger moves too fast to be human and he holds me with the knife against my neck and tells me something in a strange language and then he cuts my throat. I leave the room when he's gone and the boy and police or something are waiting outside. I tell my friend what the stranger told me and he freaks out and tells me thats the poem used to raise the dead.
I woke up all freaked out and I tried looking it up to see if it was a real poem, because I woke up convinced it was... what does this mean?
