I think the state of consciousness that the OP was digging at is addressing the concept of one-ness that is being constantly referred to in the various new age spiritual movements around the place at the moment.
The concept seems to be that on the largest dimensional level there is an awareness of being, and that perspective of awareness would be sure that seeing as it is "all that there is" that by definition means that there is nothing else.
And if there is a conscious awareness of existing at that level does it ever lead to the reflection that would cause a feeling of loneliness ?
Which goes some ways to explaining why the game of life in 3d with all its dualism and separation is happening, it answers the question "why are we here ?", we are here because it is something to do that creates the opportunity for there to be more than just ONE, even if it is all an illusion, a drama played out by fragments of the whole, the reason for the drama is what else is there to do ?
How would you come up with a solution to the problem of eternal loneliness, what could you do about it ?
Perhaps you would use your imagination to invent a game you played with yourself, a game where you pretended that you were not the ONE but forgot that in order to have adventures, and you keep going further and further out into the imagination until you find yourself here, on planet earth right now, playing at being 6 billion humans and a whole bunch of animals and plants, why, because its fun, because it's something to do, it's a distraction from the endless nothing of complete eternity and the hell of infinite loneliness.
Just a thought.
