What is it to remember?

What is it to remember?
How white the moonlight poured into the room,
That summer long ago!
How still it was
In that great solemn midnight of the North,
A century ago!

And how I wakened trembling
At soft love-whispers warm against my cheek,
And laughed it was no dream!
Then far away,
The troubled, refluent murmur of the sea,
A sigh within a dream!
