Insanity Towel - Metaphor?

Metaphor?

How are you still alive today?
Can't fool your DNA
The Body rejects the lie
Takes a certain kind to fool their mind

As it grows out of control
And delusion becomes whole
The more it feeds the more it grows
So on and on ... and on it goes

When nothings making sense
Lose the arbitrary pretence
Truth will find you in the end
In plain sight between the lines

As it grows out of control
And delusion becomes whole
The more it feeds the more it grows
So on and on and on it goes
And delusion becomes whole
The more it feeds the more it grows
So on and on ... and on it goes
