One positive symptom Ronald may have reported is hallucinations, particularly auditory ones, which are common in schizophrenia. He may have explained that he hears voices that others cannot hear, possibly commenting on his actions or insulting him. Lewandowski et al. (2009) found some individuals also experience tactile hallucinations, such as feeling sensations on their skin- Ronald may have described the sensation of insects crawling on him (formication), which felt real despite no cause physical cause. He might have also described delusions, another positive symptom, such as delusions of persecution - believing that someone is watching or trying to harm him (e.g. Thinking the government is monitoring him). Alternatively, Ronald may have shown delusions of grandeur , claiming he is a famous figure or has special powers. These beliefs would seem irrational to others, but would feel completely real to Ronald
