It can kill us.

I wasn't sure before, but after tonight I am certain. It is possible for a creature of dream to kill our physical bodies.
A few days ago, I would have given anything to know, with such conviction, that such things exist. That the world is truly as I have always believed: far deeper that its surface reflects.
And on a level, a part of me is thrilled by the realization. If this is confirmed, then what else might I encounter? What other spirits, beasts, or realms might make themselves known? What could I learn from the countless other times I have walked the earth, from those times and those places?

But, on a more immediate and personal level, there is the horror to contend with. A creature that feeds on pain, that steals from souls. A friend, new and yet old, hospitalized from spiritual torture.
We have a battle ahead of us. We are wracked with fear, and yet find reasons to hope. I am very, truly glad that I have found them all, whatever may come. And it will be very satisfying to open our war against this creature. I do believe we will win. These bonds have lasted centuries, and endure against all reason, it cannot break them with lies.
