You break a large stick from your tree, allowing it to fall to the forest floor. The dog is not impressed, and doesn't bat an eye.
You then proceed to scare the bejesus out of by getting a bit closer and waving your shadow tentacles in front of its face. The dog bolts into the woods, yelping. Following it in the trees, you wait for the opportune moment to strike. When the time comes, you drop onto it, smothering it as you rip its soul from its body. The dog bursting into flames during this process does not help matters, but at that point it's already dead. Still, the fire manages to royally piss you off, sting, and make a lot of light, smoke, and a smell of burning dog at roughly four in the morning.
On the plus side, this dog was a lot larger and smarter than the bird you ate earlier, giving you enough energy to last a week if you decided to lay low and an improved sense of hearing. However, you doubt its master will be happy to find its charred skeleton. That can't be helped.
Returning to the wood pile, you insert yourself into one of the men's dreams, weaving tales of eldrich horror, doom, and torture. Along with this, you convince his unconscious that you pose no threat and that the path of darkness is the way. You have no idea whether he'll be batshit insane, in a coma, or dead in a couple of hours though, it's not like you've done this before or anything.
Time: Just before dawn, what do?
Sunlight is bad, though at this point firelight is just a pain in the ass... or it would be if you had one.
