A sance is a gathering of people who attempt to make contact with the spirits of the dead. Sances are typically led by a medium, who is believed to have the ability to communicate with spirits. During a sance, the medium may go into a trance and speak in the voice of the spirit, or they may simply relay messages from the spirit to the participants.
Sances have been practiced for centuries, and there are many different beliefs about how they work. Some people believe that spirits are able to communicate with the living through the medium, while others believe that the medium is simply accessing their own subconscious mind. Regardless of how they work, sances can be a powerful experience for those who participate.
