And on the flipside 

The Nightstalkers:

Terrifying unformed creatures to seek a host to live and feed off of. They burrow into their dreams, fears and eventually their very soul contorting and altering the body of the host, until it no longer has the strength, the will to fight back. Those infected first lose their sense of self. They become one with the the parasite and ultimately get absorbed into the Nightstalkers depths, forcing it on a new quest for a new host.
They can live everywhere and are highly intelligent, they can allow their victims to come through and use their voice, their body to pretend everything is fine. Only in the final stages when the victim's body is too far deteriorated does the Nightstalker need to look for another potential host.
Which isn't a difficult thing to do. Most hosts don't even realize they are infected until it is far too late.

What could they look like?
