I have not read any of the other posts, because I did not want them to bias my initial response. Appreciate you sharing, some things to consisted
I see you posted on May 4th, I am very curious to when exactly the dream happened, and if it happened within 72 hours of the new moon?
April 30 (Saturday) =New Moon
This is a big deal because it was also a Partial Solar Eclipse
Which means the alignment was almost perfect!
This effect can make dreams much deeper when they occur within 72 hours of it.
The fact that your ‘diamond’ rock solid heart shattered, and it caused you to turn into a liquid and you fled/were sucked, (by gravity into the floor) is very interesting, the moon and sun are notorious for their tidal forces, and that effect is most dramatically visible in its effect on liquids (its effects on solids and gases is much more subtle). When you sleep during the nights of the week of a new moon, the sun and moon are around 180 degrees, aka on the other side of the world. So you have earths gravity pulling you down into your bed, but also, the moon and the sun’s.
Have you heard of the Diamond Cutter Sūtra?
I’m no expert but my interpretation of that Sūtra is that the truth it holds is so powerful it can cut through the toughest and hardest objects in reality, including ‘reality’ itself…
“Past mind is ungraspable,
Present mind is ungraspable,
And future mind is ungraspable.”
Very deep insight, if the true nature of reality (= mind) is ungraspable, what are you doing clinging to it ( your heart) so tightly?
You so quickly were able to question the nature of the dream
and it schizemed,
Then the dream returned the favor,
And you shattered
and melted.
THAT IS DEEP!
How ironic!
I think there is a profound teaching in the subtext:
The choice of the word STEADFAST is really illuminating.
I would LOVE to be able to ask the Buddha:
“How many things in this universe are truly Steadfast?”
If that’s too religious, I think most scientists will tell you the only (Steadfast) constant in this universe is change.
I heard Andrew say in one of his videos something like:
“ the amount we suffer is directly related to how tightly we cling to a thing/reality/mind”
The power of heart is remarkably potent, but, perhaps it was the wrong tool to CLING to in this circumstance.
How do you know that you were not communicating with something higher or the Source of all information ( God =the universe = the Matrix =Infinite information) many names, one core idea:
That ‘entity’ sees all, hears all, feels all, etc etc… it steals ALL information into itself
(Sounds a lot like big Tech, let’s assume they are not the ones you have beef with here 
I am a novice in this field, and a new but very avid student of Andrews work, and it shocks me that when presented with fear, you did the opposite of his teachings!
Fear is never something you run away from in a dream. You run towards it and confront it!
How did Hercules defeat the Hydra?
What a perfect opportunity for COMPASSION,
if these agents are the gate keepers of all your information (and possibly the universes), why not project your consciousness into them, giving you access to what they know (potentially EVERYTHING).
They symbolism of Matrix Agents in business suits is really fascinating when juxtaposed with the emotions you felt:
Cold, calculating, detached, emotionless Artificial intelligence
VS
two of the strongest Emotions known to humanity (Fear and Love.)
Maybe a better response to the Fear was not to approach it with Love,
but instead with compassion (an EMPTINESS of mind)?
That way you could understand where their ‘hostility’ or perceived hostility was coming from?
Perhaps Their ‘hostility’ was/is really Your Hostility?
This is your mind where they appeared, hostility is still perhaps a part of you (as with everyone else on this planet), and it may be a SHADOW that your awareness has not fully illuminated yet. If this is the case that ‘pure’ Steadfast Love from your heart may have been tainted, which will always inevitably cause it to shatter.
I can not project my consciousness into dream characters yet, so I am ignorant of its effects.
A Second solution, perhaps even better than that, would have been to compassionately ask questions. Not hostilely or fearfully interrogate, but asking from a place of emptiness (openness, compassion, awe, and curiosity)
What lesson are you here to teach me?
Who are you?
How can you steal all my information?
Can I see what you see?
Why did you appear when I questioned the reality of the dream characters?
Why are you blocking my path?
What is your endgame?
Etc.
Sometimes approaching situations with a mind that is FULL (full of fear or full of love/heart), will prevent the mind from being filled with anything else (information).
If Emptiness is everything,
Then perhaps it’s the solution to this riddle 
Asking the 5 Ws + H (who, what, where, why, when, How, etc) in any circumstance, empties the mind, in a way, deleting the clutter, because with each question you are challenging and killing off your inherent preconceptions and projections, which clears away space for the truth to enter.
The best communicators question, and then deeply listen.
I think your soul maybe was trying to communicate with you, but you treated it the same way you treated the initial dream characters that ‘schizemed’, you assumed you knew who/what they were.
If that is the case, it’s a very powerful lesson.
I am sorry for the lengthy post, and if it is way off I apologize.
I am new, and this is my first post on here. I have not been able to achieve lucidity on demand. I have only become lucid 5 times in my life, and each one was on accident, and when it occurred, the dreams deteriorated rapidly. I am very ignorant, so please take all the above that I wrote with a huge grain of salt. I hope it helps though, and I am very grateful for this community and the wealth of knowledge here.
