Ancestors believed that any suspicious noise in the house could be a sign from otherworldly forces. However, they did not always warn of positive events.
For example, hearing a triple knock means someone will die. They said that this was a warning that someone's soul would soon leave this world.
If there is a sick person in the house, the chances of recovery are minimal.
In addition, the following must be taken into account.
If you hear a knock, but there is no one behind the door, then this is a sign that evil spirits are trying to enter the house.
You must not open doors or windows, so that evil spirits cannot enter the home.
Hearing a knock in the morning is considered a more harmless sign. It is believed that this foretells minor household troubles that will not be difficult to deal with.
When birds or even insects knock on the window or door, you should prepare for quarrels and conflicts in the house.
