I missed this post. :( ... I know the contest is closed . But nevertheless !
Your question made my mind tick.
And this is what I want to say -

"What lies behind the closed door is a manifestation of what lies in your soul" .
The Universe outside is the reflection of the Universe inside.
The universe and destiny only play for you the story of your soul.
:) .

For me, behind the door is FREEDOM :)

My answer is for you, @onceuponatime . Hope you like it.:)
Not part of the contest as the contest is closed :)
