Brainy Bile

Those bilious thoughts
come up
hot
and thick,
chunky and acidic;
suffocating, choking
then receding
like waves
except not cooling soothing calming.
These vomitous waves of thought,
threatening more and less
more and less more and less,
bring chewed up thoughts to the surface,
the submarine filth brought in by strong undertows.
And so I am thinking
and not thinking
thinking
and not
Every oscillation more violent,
until
those thoughts
spew,
filling a brain
that can't be flushed easily
and I am calmed for a bit
while the regurgitant thoughts cool,
steaming in my head.
