Some people actually mystizize coma! They imagine a coma as some deep dream. Think! What if you have a nightmare?! And if you awake one day you will have lost the ability to use your body! Everybody can become a victim. The K.B. usually arrives together with brain trauma or a very heavy psychic blow. Some intelligent monsters learnt how to wield them! If the blanket covers you once, you cannot lift it by yourself anymore.
How to fight it
Difficult, many times one does not invite the K.B. but is attacked without any warning. Wear a helmet and hope that if you are ever hit, that there are people able to lift the Blanket. The longer it covers you, the heavier it becomes.gab
