Incubus

What is this nightmare?

my mind races
    furiously,
scrambling for          Something –
                                       Anything –
to grasp onto.
my hands,
        soaked
                       with sweat,
tightly clutch the
                             Ledge
which separates
the reality  above          
from        the
              unknown
           
              below.
                             my arms grow weak
and                              i  p l u n g e
                [into]
                the unknown.          
i can no longer            c  on t rol
myself, for
         i no longer    know
myself.                    
                             Visions dance
                             around me,
offering no clarification --
only
         deeper perplexities…
                                       ?
my ego
                        is
                subdued abruptly;
                    it becomes trivial
      in the              magnitude
of my                           
                                      Interpretations.
                        within moments,
my breath and
sanity return
simultaneously.
and i am left……..Attempting 
to comprehend
the elusive pursuit --
the essence
of existence.
