Poem with an explanation: under the red sky

under the red sky
upon the sand
the waves stopped crashing
but for a moment

In this poem, a person was sleeping on a sofa.  The person was covered with a red blanket (under the red sky) and was sleeping on a brown sofa (upon the sand).  The person had a stressful day, but in their sleep they found peace (the waves stopped crashing).  The peace lasted while the person slept (but for a moment).
