Question Reality by Jareth Valentine

Did you ever stop to think
that maybe you have gone insane?
It's not the world that's gone all wrong,
but something deep inside your brain?
Reality's not fixed, you see.
It is just as it seems to you.
To everyone, what's really there
depends upon your point of view.
The world depends on what you see,
so if my eyes were shut for good
If all my thoughts should cease to be,
would things go back the way they should?
