Do angels (fallen and never-fallen) have a subconscious?

This is not the case. They have no physical body; they have one integrated way of perceiving things and are able to see a wider array of sources of information; they have a much larger knowledge base. The problem they have is that their beliefs become distorted through time because of conflicts they have with wanting to satisfy desires of the soul that might not be appropriate in the moment, so there must be discernment and a wise judgment to delay gratification in some circumstances, to defer to others, or take a backseat altogether to allow other beings to have priority in carrying out a project of some kind, and this might end up excluding them entirely. In this respect, the angelic world is not so different than human—even though there is room for all, beings can still get in each other’s way and decisions must be made to work things out so everything runs smoothly. When there is an exaggerated concern of the ego, it can lead to difficulty in accepting a secondary place when this is perceived as representing a lowered status. This is what led to the great fall among the angelics. We are talking here about soul characteristics more so than difficulties with compartmentalization of the mind. So it is the interplay of the yearnings of the soul and how they are expressed, experienced, and the feedback from life experience shaping beliefs within the angelics, and their response to the environment and their place in it. In that respect, it is like the human learning curve, but it is less complicated because the angelics did not start out with faulty systems. They created their own dilemma through giving in to darker preferences in what they experienced and how they reacted. This was a consequence of being in a free will environment where they could indulge lesser impulses because they were serving the self and got away with it, at least for a time. This becomes a slippery slope and is what eventually brought them down—they were unable to get back to a higher state of being after a time because it gets harder and harder the more you move away from divine alignment, to make a return. All along the way, beliefs become increasingly corrupted and those corrupt beliefs become more and more the focus in choices being made and begin to represent more and more of who they have become, at least experientially. Keep in mind this is within the energetics of their expression as an angelic being and not the full dimensions of their soul. It is much like a human being which is a soul extension as well, and only a tiny portion of the soul, and can become quite corrupted and quite faulty in many of its workings, but as an independent being or manifestation of the soul, can exist for a good long while in a defective mode. This is the problem humanity faces now there are so many beings corrupted in this way that need healing and it must be requested by human to undo this.
