Oasis: Don't Look Back in Anger

Slip inside the eye of your mind
Don't you know you might find
A better place to play
You said that you'd never been
But all the things that you've seen
Will slowly fade away

So I start a revolution from my bed
'Cos you said the brains I had went to my head.
Step outside, summertime's in bloom
Stand up beside the fireplace
Take that look from off your face
You ain't ever gonna burn my heart out

And so Sally can wait, she knows it's too late as we're walking on by
Her soul slides away, but don't look back in anger I heard you say

Take me to the place where you go
Where nobody knows if it's night or day
But please don't put your life in the hands
Of a Rock n Roll band
Who'll throw it all away

I'm gonna start a revolution from my bed
'Cos you said the brains I had went to my head
Step outside 'cos summertime's in bloom
Stand up beside the fireplace
Take that look from off your face
'Cos you ain't ever gonna burn my heart out

So Sally can wait, she knows it's too late as she's walking on by
My soul slides away, but don't look back in anger I heard you say

So Sally can wait, she knows it's too late as we're walking on by
Her soul slides away, but don't look back in anger I heard you say

So Sally can wait
She knows it's too late as she's walking on by
My soul slides away
But don't look back in anger
Don't look back in anger
I heard you say

At least not today

My friend told me that this song's lyric is really hard to be understood, so I searched for it. I agree with him. It's still good, though.

What do you think the lyric means?
