The last option is both funny and serious at the same time

I’d probably think of Millennium, so vampires,

Vampires

I would say something more like a monster under the bed

I thought of using Millennium - but I didn’t want to create a confusing example. Afterall, Millennium aren’t soulless inhuman monsters because they’re vampires; They’re soulless inhuman monsters because they’re Nazees!

Why can’t it be both?

Humans
