Humming zombies?

Why can't zombies approach
Into the humming stage?
Follow their past dreams
And become engaged?

Moaning isn't that pleasant
I'd rather it be a hum...
And have zombies stumbling around
Following a beat that isn't numb

Not that lonely beat
Inside your chest
But the beat of the drum
Where compassion is expressed

I wish the only part
Of a zombies brain
Was the memory of
Past songs they hadn't abstained

This is how my dreams are
Twisted reality at ease
And this is why my imagination is full
I come and go as I please
