One of the biggest tormenting demonic spirits fighting against the church of Christ is spirit husbands and spirit wives. They are called Incubus and succubus. An incubus is a demon in male form who lies upon women in order to engage in sexual activity with them while succubus is a demon in female form who engage in sexual activity with them. These demons are not a myth, but they are real. These demons are able to have sexual intercourse with both men and women as they sleep in a dream; but It’s not really a dream, or your imagination. It is real.
