In present study ,70 years old male was brought to Physician outpatient department with complaint of abnormal behavior and insomnia. He complained of seeing women wearing bright saris and dancing in next building .At times he would hear songs but could stop it if he wished so. As he would call out the names and tried to communicate with them ,his spouse was worried about social problems due to his behavior. He had no delusions, other hallucinations, or cognitive deficits.
