Some people say it is not real, but try to tell them that bad spirits just entered their houses. They will feel insane and try to ignore it, but the unpleasant feeling will stay. In this case people haven't changed for centuries or even millennia.
Safety is one of the main needs of humanity. There is no person, who doesn't need to feel safe and well, protected of all the dangers, enemies and tragedies. Therefore, as long as humanity exists, people will try to find the spiritual way to find the state of keeping safe and well. They asked deities, created rituals and connections with the spirits. Many of the traditional, folklore and ancient ways stayed alive until now.
Protective Deities and Other Spirits
One of the most popular way of searching for protection had always been asking spirits and deities for help. The most natural to all of us way of connecting with the spiritual part of life had always been a conversation with our ancestors. There are evidences in ancient texts, that people searched for ways of honoring and connecting with their deceased relatives and authorities. However, some of these spiritual adventures started to be seen as another source of danger. The first legends about sorcery and unwanted spirits, which answered to the request of advice, seem to be as old as Sumerian civilization.
