Abzee are said to be able to physically enter people's dreams. This theory stems from the fact that these Pokémon will disappear once their trainers fall asleep, though where exactly they go cannot be proven.

If your nose becomes itchy while you are sleeping, it's a sure sign that a Abzee is standing above your pillow and trying to eat your dream through your nostrils. A Pokémon that sleeps 18 hours a day.
