Billy Joel's "River of Dreams"

I love this song and couldn't help but think of it when painting this one :)
Below are just a few of the lyrics.

In the middle of the night

I go walking in my sleep

From the mountains of faith

To a river so deep

I must be looking for something

Something sacred I lost

But the river is wide

And it's too hard to cross

And even though I know the river is wide

I walk down every evening and I stand on the shore

And try to cross to the opposite side

So I can finally find out what I've been looking for
