Affect illusions

These arise in a particular mood state. For example, a bereaved person may momentarily believe they ‘see’ the deceased person, or the delirious person in a perplexed and bewildered state may perceive the innocent gestures of others as threatening. In severe depression when delusions of guilt are present, the person believing that he is wicked may also say that he hears people talking about killing him when he is in the company of others. In these circumstances, it is difficult to know if he is experiencing illusions or hearing hallucinatory voices talking about him and attributing them to those around him.
