Dittophobia literally confirms what they are

What snow said

(personally like au wise i always just had the idea they represent cc's fears)

But probbaly nightmares and what they are in dittophobia

Mix of the first two IMO

Probably mostly bare stuff in terms of physical but the real meat and potatoes are the illusions

These are essentially the first and the second.

Physically, they are mannequins on mobile mechanisms, and under the influence of gas they turn into monsters.

The Twisted Ones is a great proof of what they are,useless mannequins that with an illusion disk become monstrous atrocities

It was in TTO, the nightmares have a slightly different origin.

Twisteds and Nightmares are the same thing,They just have a different design, name and origin

Dont the twisteds hunt charlotte?

I'm saying they're similar, but not literally the same thing. Twisted animatronics were created to capture Charlotte and could kill when the nightmares were just mobile intimidation dummies. The former look creepy under the action of the discs, when the latter are under gas.

That
