and the tide rushes in lyrics

(Ray Thomas)
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
CHORUS
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...
You keep looking for someone
To tell your troubles to
I sit down and lend an ear
Yet I hear nothing new
CHORUS
Blackbird sitting in a tree
Observing what's below
Acorns falling to the ground
He'll stay and watch them grow
