What does it mean if you dream of a dead person trying to hug and kiss you on the cheek?

The meaning depends on whether you have had a relationship with the dead person. A dream of an unknown spector or a corpse trying to embrace you would be quite a nightmare, and would reflect your fear of a dreaded event. On the other hand, if the dream is about a beloved relative who has passed recently, then the dream is an expression of comfort and an assurance of the bonds of love and care that continue beyond the end of this life.
