These symptoms are known as "positive" symptoms of schizophrenia.
The symptoms of schizophrenia can be separated into two sorts: positive and negative. These are not positive and negative like you may think; a positive side effect isn't really great, for instance. On account of schizophrenia and other mental issue, a positive side effect is one that includes a conduct, thought or feeling, while a negative side effect takes away a conduct, thought or feeling.
