I'm really unfamiliar with this kind of poetry, but I recommend a writer, Shi Tiesheng, especially some ideas in the poetry collection "Broken Pen in the Cracks", which can help us better understand the patient's mentality. The following is one of his poems.
The last exercise
Author: Shi Tiesheng
The last exercise is to walk along the cliff.
What I heard in my dream, the soul
Like a flying fly
The window buzzed.
Dancing and singing in the trembling sun
Expectation is memory.
Who says I'm not dead?
Before birth, the sun
Experienced countless ups and downs.
Long time is wasted by long nothingness.
Swallow, in the name of my birthday.
make a comeback
In the afternoon, if the sun is silent.
Can you hear the past?
Where have you been?
At the front end of light or the extreme of thought
The existence of time is ignored.
Same life and death
