Last night I dreamed that I was come again
Unto the house where my beloved dwells
After long years of wandering and pain.
And I stood out beneath the drenching rain
And all the street was bare, and black with night,
But in my true love's house was warmth and light.
Yet I could not draw near nor enter in,
And long I wondered if some secret sin
Or old, unhappy anger held me fast;
Till suddenly it came into my head
That I was killed long since and lying dead-
Only a homeless wraith that way had passed.
So thus I found my true love's house again
And stood unseen amid the winter night
And the lamp burned within, a rosy light,
And the wet street was shining in the rain.
Clive Staples Lewis
