A Full Moon happens when the moon is on the opposite side of the earth from the sun. The moon is completely lit by the sun during this phase. The full moon has great importance for both the natural and supernatural in many folklore, stories, and mythology. The ancient Greeks believed that the goddesses Hecate and Hera made the moon look like a bride to show that her marriage to Zeus was peaceful and without conflict. They also said that the moon was responsible for madness. In Africa, there are many cultures that believe the Moon affects life on Earth and even people's minds. In some tribes, such as the Yoruba, it is common practice to ask the Moon questions to find out what will happen in one's future. If you don't get an answer, they say that it means that you will suffer some kind of misfortune. Even though science has proven that the moon does not affect weather or anything else about our planet, some people still think that it does. Scientists call this belief "lunacy." Lunacy is a mental illness where people believe things that aren't true. There are different types of lunatics, but all have something in common: they feel compelled to talk to inanimate objects or even walk through walls.
