Death or Angel

My heart stops,
time stands still.
All around me,
light.
A figure,
hard to make out,
walks towards me.
It whispers,
"Come."
Though a single word,
seeming small,
insignificant,
but that one word,
would change my life,
or erase it.
"What will happen?"
An innocent question,
you may think,
but it could kill.
