is it all inside my head Video (MV)

There's no light without a darkness
Pleasure's relative to pain
It takes climbing up a mountain
To see how low the valley is
Can't you see the glass half empty
Can also be half full
Harmony's akin to chaos
And black inverted is just white
Tell me why was I created
What's the meaning of all of this
If you dare to look behind the curtain
See the shadows aren't real
Just imaginary figments
On the walls of Plato's cave
Can't you see that I'm a skeptic
Can we know something for sure
I guess that there's no real answer
But I doubt that God is dead
Is it all inside my head
Is it all inside my head
Is it all inside my head
Is it all inside my
Head
