while nightmares are what first comes to mind, there is something greater in this particular "dot". Here, the idea is a portrayal of us reliving our sorrow and our loneliness, which is the inevitable leading of our demise. We want to escape that vicious cycle, and break free from all those "horror" which have rotted away our "sleep" (i.e. plagued our minds, destroyed our thoughts, made us incapable and vulnerable) and this has led us astray from the "flock" (i.e. our sanctuary, our home). Which is why the wolf "grins". Frankly speaking, it reminded me strongly of KathrynODriscoll. Just wound up feeling as if the theme here - which I view as rape and subjugation - is written well in two stanzas.
