sleep is a currency

sleep is a currency
whose price
fluctuates in
tender
sometimes
it is worth
the exchange rate
other times
its worth
devalues
everything else

sleep is a currency
whose pace
fluctuates in
tides
sometimes
it is deeper
than you are tall
other times
it is shallow
the enemy of
progress

sleep is a currency
whose presence
fluctuates in
time
sometimes
it is gentle
in daydreams
other times
it is indefatigable
never satisfied
with substitutes
