the easiest way i could explain it would be to say it's all a metaphor, up for interpretation. I meant it one way, it can be taken any way, which is what i love most about poetry.
broken down into stanzas the way i was thinking when i wrote it

stanza one
There were rumors you stood tall
In the cool summer breeze
There were truths in glasses
Confused murmurs gathered in masses
Till brown changed the leaves
And here in this room
I can hear
The tapping of souls
Dancing across heavens doors, and into the womb
-We talk all our lives about death and the moments after, these "rumors" seem to control us and make us, time passes, things change, we leave this life to enter another "womb"

Stanza two
There were questions we all left out
About the last night of our lives
There were answers in clouds of gas
And billowing fires and shards of grass
Till the fire stood still
And time stopped short
I can feel
The breaking of consciousness
Walking back to the hole it left, and into the chambers of solitude
-the "clouds of gas" to me wasn't intended to be a bomb, but a conversation in vapor as you walk with someone on a cold winters night (as time still progresses), however i am enjoying the visualization of the bomb here, it adds an urgency/drastic level to it. "and time stopped short", was intended to evoke the idea of the moment before death, clarity, suddenness, a full level of consciousness and awareness, you know everything but everything is strange.
The bomb idea works well again here, as the narrator enters back into the hole it left, and reflects on the destruction it left, however there are many "types" of bombs...

Stanza three
There was darkness all around us
And the night wouldn’t end
There was light in your harness
Till the black turned to grey
And there in that room
I could taste
The burning of bodies
Branching out to the sky, and into the emptiness of the night
-who is to say what is waiting for us, we all have different ideas... i have a feeling it is what we make it. So the narrator is saying there was darkness everywhere but in the one he wanted there to be light. the burning bodies was his post death, memory of his death.. plumes of souls and ashes fly into the sky, to heaven.

Stanza four
We all walked backwards
We all talked around
The things we feared and the things we’d planed
When we were younger
The mirrors wouldn’t show us
It took time to realize
That we are all dead men
-how much could you regret when you die, if you could even look back? we walked backwards and talked around the things we regret, to want to relive...

Stanza five
There was calm relieving feeling
As our boat sank into the Atlantic
There was an agitated strained weight
That was held on our backs
We watched the fire
From a room under water
And in the general ways
We died
-the abyss of death, of emotions, of love, of regret, of everything, lost into the cold darkness of the Atlantic. its relieving to see it be lost, as well as annoying. the fire from under water was to express hopelessness, as in you could put the fire out if you were not stuck below. i envisioned people pounding on the glass windows of a large boat to be relieved of drowning, to let the water killing them kill the flames. to escape death and all the abyss. but in general ways, it all ends.

I hope this either sheds some light on my intentions of the poem, or drops you further into confusion which evokes more reading or reflection. i truly appreciate you taking time to read my poetry, it means a lot to me!
