"Helloi Oknaba" (lit. "Encounter with Hellois" in Meitei) is one of the most common events of meeting with supernatural beings in Meitei folk stories. Challenges to or conflicts with the hellois often make one's life unhappy. In such cases, one may get sick, mental imbalance and temporary madness. If such people are not properly treated by a maiba or a maibi, the symptoms may continue long. It may lead to permanent madness (mental impairment). One who meets a helloi often acts in abnormal and mentally challenged ways. For example, the victims may not be able to recognize his family members and friends. However, the victims could still communicate with the very helloi. The spirit may not easily leave the victim. She will demand something in return to leave the victim. Thus, Hellois seek their needs by bewitching people.
