what are those?!?

pound,pound,pound
goes the clock
in my head
i just wish i was dead
pound,pound,pound
goes the clock
in my mind
my brains lagging behind
my bloods got to boiling
my head starts to bang
my stomche starts toiling
but it aint no thang
its real easy
to fake a smile
when you've been
doing it for awhile
if your mask
starts to slip
if your world
starts to tip
all you can to
keep your feelings
hidden
is
fake your way through
i cant help it
for me or for you
i feel a headache
coming on
now my mind
is offically gone
