all things break - Doors I Can't Open

I used to have a map, but the lines have all dissolved.
Now I'm standing at the threshold of a puzzle never solved.
And I keep walking, but the room's all look the same.
And I keep talking, but I can't remember my own name.
Doors I can't open anymore.
Standing outside, what I came here for.
Every handle turns the wrong way 'round.
I'm reaching, but there's nothing I have found.
