This is probably a bit hard but when you realise what it is, some people will go "ooooohhhh now I recognise it!"
Is it a kind of dream,
Floating out on the tide,
Following the river of death downstream?
Oh, is it a dream?
There's a fog along the horizon,
A strange glow in the sky,
And nobody seems to know where you go,
And what does it mean?
Oh, is it a dream?
