Otherworldly

I don't need a house to be haunted,
these legions consume my mind.
For in all their midnight meetings,
I'm the one confined.
I walk this barren land,
an external ghost roaming free,
these walls don't speak of treason,
the only haunted here is me.
An assassin with a revolver
playing roulette at three a.m.,
they've got me in their sights.
I should startle if just pretend.
For myself, I am concealed.
Their weapons, firing synapses,
in attempt to hush these demons down,
my brain often relapses.
