The Fortress of Solitude.

Somewhere deep within this fortress of lies,
Lies a man deep within his own disguise.
It's Where he hides when his heart begins to sink.
And where he runs when he's had too much to think.
What part is real and what part is not, who is to say?
It only matters that it keeps the truth far away.
And yet, it matters not, the realities he creates and perceives,
But more so in which fiction he truly believes...

I really like the first two lines, and the very last line. The rest is...Eh. At least it rhymes.

Negative feedback is appreciated.
