And the Tide Rushes In

I've been searching for my dream, a hundred times today
I build them up, you knock them down, like they were made of clay

Then the tide rushes in, and washes my castles away
Then I'm really not so sure which side of the bed I should lay
I should lay-ay-ay-ay

You keep looking for someone to tell your troubles to
I'll sit down and lend an ear, yet, I'll hear nothing new

Then the tide rushes in and washes my castles away
Then, I'm really not so sure which side of the bed I should lay
I should lay-ay-ay-ay

The tide rushes in and washes my castles away
Then, I'm really not so sure which side of the bed I should lay
I should lay-ay-ay-ay

Blackbird sitting in a tree, observing what's below
Acorns falling to the ground
He'll stay and watch them grow
