Nightmare/dream Haunts

The Nightmare Haunts are creatures in Kaechaek that are powerfully formed from massive spaces of realisation, to a point that the amount of dreamers and nightmare havers causes realisation to 'spill over' excessively. 
It is relatively rare to run into Haunts but, when one does, they usually travel in packs or are 'bound' to a spellcasting of power... usually a member of The Unwaking Coven.
