Classic Poem

When Narihira went to the province of Ise, he met in secret with one of the priestesses of the Ise Shrine. The following morning he was fretting because he had no way to send her a message, when this poem came from her:
Did you come here?
Did I go to you?
I don't even know —
Was it a dream? a reality?
Were we sleeping? were we awake?
Reply:

I lost my way
in a darkness
that blinds my heart —
dream or reality —
let the people of the world decide
