Tobias and his biological mother have both been diagnosed with schizophrenia. Tobias experiences vivid visual hallucinations, frequently seeing shadowy figures moving in the corners of his room. He also suffers from persecutory delusions, believing that a local secret society is monitoring his thoughts and plans to poison his food.
