Is It Really Real

Could it be,
That the world isn't really what we see?
That we are all insane,
And there isn't any sunshine, any rain.
That everything we see and feel,
Isn't really real?
Could it be that the Earth is just a ball,
And slowing getting ready to fall,
Through the atmosphere,
And kill us all?
Could it be that there isn't really a sky,
And we're just sent here to die.
That the world isn't what we like to think and take
But that the world is really fake.
That people aren't truly here,
And this is what I truly fear.
Could it be that life is just untrue,
And there's nothing we can do?
