In the kingdom of blue and grey sadness tints the emotionless hearts of men just willing to go to sleep.
Days are to be hated, looking in anger at the black daysky from the insides of our caverns, away from the hurting rain which wears out feelings.
And we'll gather around the fireplace, sinking our hearts in liquid darkness that lights them up while peeking into other worlds.
But the dreary atmosphere still be poisoning our souls, the ghostly shades of them, leftovers of our true selves,
Then, go to bed and sleep! Give up! And in your fortress of sweet soft blankets, dream of a new dawn in a new kingdom.
This poem refers to those cloudy days when everybody feels a little bit blue and we are in no mood to do anything, just wanting to stay at home. The third stanza might be the most allegorical one, though the metaphors are not about transcendental subjects: liquid darkness is hot chocolate or coffee, it depends on what you like, and the paradox in "darkness which lights" reflects that in cold days when everybody is at the living room, hot drinks usually cheer up people. The last verse, peeking into other worlds" is a metaphor for reading books. The next stanza was about the same that the first and the second, and the last one is quite literal, the new kingdom is a new day which perhaps will be a sunny one.
