Sleepwalking

I must have had a nightmare
Cos I'm not seeing straight
The shadows creep and slide
The strangest thoughts
Go through my head
Outside the traffic lights
They change from green to red
And as my heart applies the brakes
I reach across the bed

I was in a dream
You were by my side
Warmer than the sun
Then the picture changed
Began to fade away
Turned and you were gone
Sleepwalking

Could that be somebody
Standing on the stairs
I can't ask you
I can't find you anywhere
So why are you out walking
Walking in my sleep
And what goes through your mind
Each time you lie between the sheets
