A Nightmare in Poetic Form

(Note:  Inspiration for my poetry is derived from the Dreamtime.  Occasionally, a nightmare will evoke the creation of a short story.  A recent nightmare continues to haunt me, so I have attempted both forms of literature to garner new meaning.  The poem follows and the prose version can be seen here.  Which form offers more insights I wonder?  objectivity in the form of comments appreciated.

Nightmare:  A Poem

Melancholy hovers, haunts,
fed by isolation, taunts
threads of sanity.

Darkness, incomplete,
reveals movement –
trickery of light?

Fear’s grip renders
motionless its victim
serenity shattered

Logic has no tolerance
for the undefined,
ghosts off-limits

Is disease the culprit,
inflammation upsetting
equilibrium, a mind aflame?

The veil between worlds
is flimsy, unhinged, shifts
awareness now peaked

I know you are there!
Show yourself!
Stillness.

Madness threatening,
pleas gather insistence
Come forward – be known!

These are merely games
one reality pit against
another, neither winning

A feminine figure emerges –
her presence emitting an aura
of alarm, indicates a window

Two figures, cloaked in black
towering shadows stalking
live prey, the scent of vulnerability

The ego withdraws, seeks
cover, cannot stop the onslaught
of monsters emerging from walls

Delusion, one last prayer for sanity
but the floorboards recede, reveal
skeletons, there is no escape
