Hi,
Here I offer some substantial feedback on your work as I held this poem in such high esteem that I thought it would be deserving of an extra effort, thus the critique. Apologies if it isn't helpful.

This meditation on Memory, Fear, Youth and Death struck me as at once childlike, yet somehow, through such strong perceptions and observations, the work of someone wiser and older.

The narrative, discussed with a sibling or close friend (I still have nightmares about mom) (?)is deeply personal and almost confessional in its tone.
I enjoyed the analogy of waking from a dream gasping for air, like being saved from drowning, hooked and pulled up to the surface, rescued from the nature around you.

You continue well with your observations of the contrasting nature around you

Always summer,
but always cold.

and

It was still light out
and the sun sifted
through the oak trees
to the old terrace.
The air smelled wooden,
ready for fall:

both conjure excellent images as does the observations of the cold feel of a rabbit, mixed with the warmth of the fur, and

I was eight when I learned
rabbits are still soft after they die;
their eyes become milky.

has such a childlike innocence.

Memory is a highlight of this work,

they way that you empathise with the loss of a brother

I remember as she remembered

shows empathy to the one who lost a brother and imagination and memory in 5 simple words, as we gain a vision through your visions.

Memory is heavy throughout and I like the way your viginettes and snippets are not always yours and other times are so deeply personal,

It's enough to look in the mirror
and see my mother blossoming forth

is a generational line only a daughter could write.

Through the senses

of cigar smoke,

and

dust motes suspended
in wet, stagnant air

we are engaged and delivered to the present.

I loved the tone of the piece, a lament on death and sorrow that has a raw melacholy throughout

Even before I knew, this house seemed
frozen like a photograph,

and as I said, it had a high impact on me due to its confessional notes and beautiful vision on basic lifetime observations of loss. Like a person trying to be braver than what they really are.

Technique..? Well I am not in a position to judge to much, as I am a free form poet and I don't believe emotions and structures go well together, I loved the loose form, you had some moments where I would have placed commas that you did not and I perhaps would have been a little more consistent about the attitude toward death itself, as it was a little ambigious, but perhaps purposefully so.

All in all your work engaged me, brought visions to my mind and a sadness to my heart inside a strong narrative structure.
Death, loss, memory and nature, you tackled all the biggies well. Congratulations.
