Because Dream requires Light, Dark, and any two other elements. You are not fulfilling this requirement.

You have Light, Dark, and another element (Air), but no fourth element.

Mirage contains Light and Dark, and Hypnotic contains Light and Air. Therefore, you would need an additional element (in addition to Light, Dark, Air) in order to breed Dream.
