Dreaming about visitors could represent terrible or positive things in your subconscious.
It can represent positive developments such as the presence of clairvoyant power. Sometimes this power takes form. These are spirits such as wandering souls or even deceased relatives who cannot forget your worries and show up to keep you company while you sleep.
The visitor in the dream could signify benevolent spirits waiting for you to help them across a difficult crossing. Also, you will prepare to welcome a powerful deity as they want to come closer to divine contact.
