Unclean spirit

An unclean spirit is something that is naughty, mean, or bad. It's like a bad ghost, or a bad spirit, that exists in a space and makes it hard to be happy or good. People think that unclean spirits can try to control people, like when something bad happens in a place it can be because an unclean spirit was there. People might do rituals or prayers to try to get rid of the unclean spirit and make a space peaceful or happy again.
