A spiritualist is a person who believes in the idea that the spirits of dead people can communicate with living people, often through a medium.
Some people think of spiritualists as mysterious or strange, while others think of them as kind and helpful.
Examples:
The spiritualist spoke to the ghost.
My aunt is a spiritualist and she talks to spirits.
The spiritualist helped the family talk to their grandmother.
The spiritualist knew what the ghost wanted for dinner.
The spiritualist can talk to animals and plants, too.
