The song All In My Head is performed by Katie Melua .
Every night we fall into bed
But it's all in my head
Every night we fall in a heap
And you kiss me to sleep
And baby, all the sleepy things you say
Blow me away 'til the next day
When I find what we did and we said
Was all in my head
Every night you whisper to me
This always will be
Every night you smooth down my hair
But you're not really there
And darling, it seems as if we know
Our love will grow, then the next day
I find what we did and we said
It was all in my head
Drowsy, drinking, I keep thinking
We're not far apart
Scared of waking, lonely, aching
Just me and my hopeless heart
Sleeping soundly, your arms 'round me
Through the night we cruise
Then I found it's in my mind
That you stroke away my blues
Every night we fall into bed
But it's all in my head
Every night we fall in a heap
And you kiss me to sleep
And baby, all the sleepy things you say
Blow me away 'til the next day
When I find what we did and we said
It was all in my head
It was all in my head
It was all in my head
