i hear very true to life auditory hallucinations when im very tired and on the verge of falling asleep, what they say is always somebody that I know's super accurate voice rambling on, simple language pieces and nothing of substance or actually topical usually. i listed to them but when i become more acutely aware of them and start overthinking about them they disappear. or when i raise my head and stop being tired. This is similar to closed eye visuals where they get very detailed and interesting until you start trying to focus on the visuals and then they just vanish
