I actually liked how the Mist is confusing. It does two things:

1)It makes it mysterious

2)It lets you make your own ideas and theories on how it works.

For example: Pasiphae passes through a trapdoor that doesn't exist. This might be her doing it to herself. She subconsciously used her powers to fall through the ground because she thought she was going to fall through the ground.
