i played zombie games, and the blade was a brush cutter, one that i own, sitting in my previous place waiting for me to recover and bring here to hang on the wall... it's like a hand-scythe

and i figured that the game had something to do with it (in the game bladed weapons are especially effective especially if you lop their head, and scythes especially, though during my session i was only using large knives) but i think that there was also an aspect of "wanton destruction of stupid people's illusions is kinda pathological somehow" in the dream

it wasn't serious, just sorta like, i was being indulgent
