I have this theory that dementors cloaks are actually lethifolds, for several reasons:
1)They're both black.
2)The Patronus charm is the only thing that works against two things: Lethifolds and Dementors.
3)If I remember my Fantastic Beasts and Where to Find Them correctly, you get a cold feeling when you're around a lethifold as well as a dementor.
4)Harry described the dementor's hand as looking like a corpse that had rotted in the water.
Can lethifolds drown? Maybe one went to attack a human and fell in the water before it could digest it completely, then some kind of hocus pocus turned the two into a dementor.
Just wondering what everyone thinks.
"You're disturbing...yet intriguing. Like couscous. I'm gonna call you Couscous from now on."
Hmm, I don't think they are. It would have to be a symbiotic relationship. I just don't see dementors and lethifolds having anything to share.
"This dangerous beast resembles a half-inch thick black cloak which moves along the ground at night, hunting its prey. It attacks sleeping humans, smothers them, then digests them, all in their bed, leaving no trace at all. The only defense against a lethifold is a Patronus Charm. Thankfully, this frightening creature is rare, only found in the tropics "
I don't know what a Lethifold is, but I do like how CelticDragon came up with that theory There's a couple of interesting connections there... though I gather Fuscia knows what she's talking about when she says it's probably not true. Still very interesting
