I have undergone a "hearing voices" exercise as part of law enforcement Crisis Intervention Team training.
You wear a headset and various voices...sometimes right ear only, sometimes left ear only, sometimes two or more voices in both ears saying stuff like "you are a loser" or "you are such a rotten creature that you do not deserve to live".
In training there is a volume control.
In real life there is none.
That sounds like an average Russia/Ukraine thread.
