What do these lyrics mean, do you think?

[raccoon]

I'm a cork on the ocean
Floating over the raging sea
How deep is the ocean?
How deep is the ocean?
I lost my way
Hey hey hey

I'm a rock in a landslide
Rolling over the mountainside
How deep is the valley?
How deep is the valley?
It kills my soul
Hey hey hey

I'm a leaf on a windy day
Pretty soon I'll be blown away
How long will the wind blow?
How long will the wind blow?
Ohhhh

Until I die
Until I die
These things I'll be until I die
These things I'll be until I die…..
