Exactly! They are a physical projection of his own subconscious desires. He has no control over them. His "mental" blockchain being able to store everything he physically sees and hears, but his subconscious has also learned to create and imprint it's "own" version of what it wants to see and hear onto the same blockchain too. Hence, his subliminal wish to resurrect his dead mother from the grave is actually happening because deep inside, that's what he really wants!.

Our subconscious thoughts usually manifest in dreams, where you can actually believe you are somewhere else and it can feel so incredible real at the time. Except in my story, those dreams are brought into literal reality. Plainly seen as clear as you see everything in front of you right now.

Lol! Again, I'm waffling! But that's how deeply I've thought about this one! Sorry!!!
