"That is nothing. Just a hallucination. Unreal and comes from an imagination."

I'm sorry, but if you knew anything about the Gravity Falls universe, you'd know that the line between concrete reality and illusion is very blurry indeed. There are demons of the mind that can make you go insane, and you can summon them to steal knowledge from the subconscious of a sleeping person. You could even use them to bring your wildest dreams to life.

So no, Aoshima is not "just a hallucination", as you claim. Perhaps in the Fallout universe, but in Gravity Falls, he's just as real as anything else.
