How do you sleep?

justam

Some people have frequent nightmares
they toss and kick
having visions of evil doings
and jagged implements
monsters
hidden pursuers behind
they might wake up in a cold sweat
with half-remembered terrors
but
other people sleep more soundly
maybe they dream of love and peaceful landscapes
there's a theory that it's merely poor digestion
acid reflux?
but who really knows what causes bad sleep?
