Urgent necessities are delayed and disaster strikes because a slothful man hid behind the curtain called, sleep. Cities have been invaded, the critically ill have died, destruction has consumed nations because someone was sleeping, who should have been awake. Jonah tried to hide from the call of God in his life. Because of fear, he buried his God given responsibility in the state of self induced slumber. He thought the call was like the night, that one can simply sleep away and when he awakens in the morning, it's all gone.
Saints go to sleep spiritually.
They go down in the ships of Pleasure, employment, and education for months and years. They bury themselves away in the hold of spiritual indifference. The five foolish virgins slept away precious moments that they desperately needed to acquire oil in. They wasted the golden moments in slumber. King Saul slept while his enemy cut off a portion of his garment, stole his staff and his precious cruse of water.
