Mnemonic

Closing your eye is what people do when sleep calls. Picture a stadium full of people — one by one, every eye shuts, heads nod, and a great wave of sleep rolls across them all like a spell.
Additional thoughts
Eye + People = Sleep. Visualize a contagious wave of drowsiness sweeping through a crowd, every single eye closing in sequence like dominoes falling.
Quick recall
Eyes of people shut as sleep sweeps the crowd.
