Delirium tremens is an acute and sometimes fatal brain disorder affecting alcoholics, sometimes called alcohol withdrawal delirium, which happens a few days after one stops booze intake of many years. Symptoms may include raving, hallucinations, trembling, rapid heartbeat, among others.

There is also alcohol hallucinosis which is associated with years of constant alcohol abuse.
Now, in slang use, it's the d.t.'s, the heebie-jeebies, the shakes, the blue devils, when those pink elephants turn nasty. Delirium also accompanies abuse of drugs like amphetamines. It may be of slow or rapid onset.

..tied to a fading memory
of something lost in time
afraid to make the change
scared to leave the past behind

I stood at the door to a new beginning
the future called and frightened
I turned away

leave the past behind
the long road lies ahead
close your eyes, forget the fear
leave the past behind..

..Inside black decision concealing what no one knows but I
To regain the vision that my freewill once cast aside
Tomorrow Turned Into Yesterday
The sweet downhill sadness of our slow decay
Tomorrow Turned Into Yesterday
And I see the fault of the steps that I mislaid
Tonight the north wind spoke to the trees
And said, 'Open your eyes'
Deep silver glimmer slither, drip down
And emoition dies, emotion dies
Tomorrow Turned Into Yesterday..

..A flower to behold
Don't run. Don't blow away
Breathless to my eyes
So bright. Never to fade
Calmness and mystery
Entwines and captivates me
Delicate to the touch
From what I could see
I only wanted to get you close to me..

The self-mutilation
The destruction of myself
Fear disappears into sweat desire
The dreams of remembrance
The fear of realityConfused creatures created by bizarre pictures

Faces of immortality
Faces of the unknown
Faces of death
