i had a weird scary NCIS dream

I had a weird but scary NCIS and NCIS Los Angelos crossover dream where there was a huge city wide militia riot where everyone was using grenades, shotguns, pistols and uzis.

that riot storyline involved both shows

then there was another storyline that went on in regular NCIS where Hunter and couple of other younger agents got hurt and died real bad from a tragic accident in a garage where they got hit hard by shards of glass that sliced off the top of an agent's head exposing the brain and another agent instantly dying from a large piece of metal.

all caused by a lawnmower and something that looked like a battery charger or something that was sparking and leaking fluid causing an explosion in the garage
