This echoes the popular wisdom that benzos can only mollify hallucinations to make them bearable, and then force a black-out at higher dosage. Antipsychotics (like Seroquel & Olanzapine) on the other hand make the visuals and 'shadow people' (hallucinations resulting from lack of sleep) disappear, forcefully flinging people back to a semblance of reality, and then to uncomfortable sleep.
