In illusions such as those, it is not so much that I am recreating them. Rather, my eyes are reflecting your own memories back to you; sometimes just as you remember them, and sometimes twisted so as to be more cheerful... or, perhaps, more frightening.

As a matter of fact, I cannot see the illusions I create. Just as you are not really talking and walking around, neither am I really doing anything but standing in front of you silently, watching to be sure the illusion is not interrupted by any creatures that might be in the area.
