Night Castle

I have been this way before
Check each window, every door
For a passage through this night
This nightBut each hallway ends the same
Every door's been checked in vain
For a way to reach that light
That lightAs I move in deeper
Towards this castle's keeper
Every stair seems steeper
Am I risking my own life?
My lifeThen a falcon in the air
Looking down returns my stare
While she's circling around
AroundThen she dives straight towards a wall
Then she isn't there at all
And is gone without a sound
No soundI have no choice but to follow
What was solid now is hollow
Stairways hidden behind curtains
Realizing nothing is certainSuddenly upstairs I'm climbing
Then through hallways twisted, winding
This falcon on her endeavor
Do these stairs just go forever on?And in that room, an old man sitting there
He's writing notes and drops them in the air
Somewhere outside upon an ocean breeze
Which takes them out past where the eye can see
