Mumbling mumbling 
It started with mumbling
Lips quivering
Vibrating
Lightning speed
Incoherent mumbling

Growling growling
Then came the growling
Guttural moaning
Interspersed
Deep resonance
Bellicose growling

Talking talking
Soon came the talking
Ominous words
Somniloquy 
Threatening phrases
Speaking and sleeping 

Shaking shaking
And now I am shaking
In the other room
Separate 
Petrified nightly
Awake and shaking

Walking walking
Next came the walking
Following me around
Attached
Mumbling growling
Mindlessly walking

Screaming screaming 
Now he is screaming
Incessant howls
Unyielding
Shattering silences
Walking and screaming

Sleeping sleeping
Only while sleeping
No memory
Obliviate
Dismissive laughter
He was just sleeping
