capricious: (adjective) an outcome driven by sudden, unpredictable change

your head gets heavy
a feeling of doom springs about
it lingers
enveloping you in fumes of doubt
it sets in, a cloud above your head.

it takes control
a silent, grey dread

colours fade out,
light grows dim
the heaviness spreads,
filling your eyes to the brim
shades of grey is all you can see

you search for colour,
desperately
to bring you back to reality

for the world you knew
sinks beneath the tide
into the dark abyss
of your mind
where shadows hide.

the abyss becomes all you know.
