Rare eyeless variants of Unzee exist that behave even more aggressively, sending out their thralls of Unown to send as many victims as possible to sleep so it may gorge endlessly on their sweet dreams, leaving only nightmares behind.
If your nose becomes itchy while you are sleeping, it's a sure sign that a Unzee is standing above your pillow and trying to eat your dream through your nostrils. This Pokémon is shaped like ancient text characters.
