From a psychiatric perspective, hallucination are different from illusion.

Visual hallucination are non-existing imagery that comes from your head without any actual external stimuli. Visual illusion are non-existing imagery due to a misinterpretation of an existing sensory stimuli.

Emerald's power seems to be inserting hallucinations (causing Amber to see a little girl despite nothing was there), while Neo's power appears to be more of illusionary nature (you still see her from your eyes but it is in fact some sort of physical mirror image of her).
