Dream Guardian

It's called the Dream Guardian, it is a being that absorbs nightmares so other creatures around it can sleep easier.

At it's base state it looks like a small white wolf, the anatomy is kind of a mix between a wolf and a racoon, with it's legs a bit on the shorter side. The eyes are colored like an amber stone. 

The tail may look like a horse tail but it is more similar to some kind of pointed draped fabric. That tail hardens up to become long and tough spikes if self defense is needed.

As it absorbs nightmares through the little dreamcatcher on it's snout, it becomes darker and darker, sometimes looking like it has bathed in tar at it's maximum capacity.

Since it isn't a normal creature, it doesn't need sleep most of the time, it doesn't have any reproductive or digestive system too.

When it is at full capacity, it sleeps for 1 night to dispose of the nightmares into some other dimension. Even it doesn't know where they go, but it doesn't really bother it.

Talks through telepathy.
