I will explain why solopism is bs first. Though your consciousness is merged with the “all consciousness” in a single medium (aether) your consciousness is unique it is not one thing, it is subdivided in fractals. The best way to model this reality is to always use computer science references so I will say think of your hard drive on your computer, it is a single hard drive yes but it has countless files it, are they all separate files or one file? Thry are both but magnetic fields separate them from the whole. The aether is the same way, yes the entire aether is one single consciousness but it isn’t your consciousness, you are not the “dreamer” so to speak, you are just one of the partitioned files (both figuratively and literally). You have a toroidal magnetic field that partitions your “you”, “self”, “I”, everything in this aether does. Think of it as an invisible liquid just like the sea, billions of creatures live in the sea and the sea could be considered one organism from one perspective but of course we know all of those objects in the sea are acting separately in their own self interest AND together in their ecosystem. The ocean is their medium, the aether ours. (Of course they are in the aether as well on top of a more dense aspect of it the water].
So each individual person is having their own experience, no you aren’t the “all”, it is orders above your tiny consciousness and processing capabilities, it can process the entire matrix from its perspective we as humans in these avatars can process very little. Most humans are ant consciousness on auto pilot, literal NPC.
You can also think about it as your graphics card on your PC for gaming. Is the graphics card and the main processor separate or one (we are subprocessors [graphics cards] under the main processor [motherboard processor])? Well it is both, the main processor sends all graphics info to that graphics card that it partitions out separate from what it
