Threat to a ghost

Go away or turn back
turn back you creep
turn back and show your face
before I go to sleep

don't have room in my head
for nightmares to keep
have my fears floating around
from within deep
thud thud my heart is pounding
sweating all over eeep

there in the corner don't you float
show me the real you take off your coat
better make it happen before I slit your throat
