A spiritualist church is a place where people go to talk to ghosts and spirits. They believe that when people die, their spirits go on to another place, but they can still communicate with us. People who go to these churches listen to messages from these spirits, and learn to talk to them themselves. They also do things like meditation and energy healing to connect with the spiritual world. It's kind of like talking on the phone with someone who is in another country – you can't see them, but you can still hear them and talk to them. Some people find comfort in this kind of communication and believe that it helps them feel closer to loved ones who have passed away.
