We do not know what AUM's perceptions are like. AUM has no sense organs. That comes with being in a PMR VR and its rule set.
The Void state is largely the goal of meditation, placing oneself as an avatar in a state of maximum receptivity with no stray input to compete with the input from the LCS Guidance which is the ultimate goal of meditation. But this is ultimately a way station also as you can go on to being open to communicate with guidance at any time or state of being. An open communication channel with the LCS.
My understanding is this is what it experienced in its early stages of evolution. Before it realized it can change itself and be in different states. What Tom describes as “I can exist in this state or that state” and it realized it can change itself with intent.
While Tom Campbell does state this within his books, it is metaphorical and descriptive, not literal. This is actually describing something that would have happened before consciousness developed, not a description of the actual thinking process of AUO as consciousness would not have existed at this state being described. This is a metaphorical description of the process of learning to be conscious, not a literal description.
