Fear of the dark

"[...]When the light begins to change
I sometimes feel a little strange
A little anxious when it's dark.

Fear of the dark,fear of the dark
I have constant fear that something's always near
Fear of the dark,fear of the dark
I have a phobia that someone's always there

Have you run your fingers down the wall
And have you felt your neck skin crawl
When you're searching for the light ?
Sometimes when you're scared to take a look
At the corner of the room
You've sensed that something's watching you[...]" - Iron Maiden, "Fear of the dark"
