A Deceased Person Marrying a Living Person
Scholars have stated that if one dreams of a known deceased person marrying a living person, it might indicate that the living person will receive goodness from the deceased's inheritance, or from their heir or offspring, whether it be knowledge or other benefits. Kissing in a dream, however, is interpreted in reverse to marriage, where the doer receives goodness from the one being kissed and accepts from them.
