I saw this door in the alpes this year. Thinking about words to the picture a beatles song came to my mind. Nowhere man could be living behind this door.
update: Now I came across the perfect song to this picture
"The Alan Parsons Project - A Dream Within A Dream"
We come to the world from nowhere to in the end go nowhere.
