To dream of seeing a priest at the altar, denotes quarrels and unsatisfactory states in your business and home. To see a marriage, sorrow to friends, and death to old age.
An altar would hardly be shown you in a dream, accept to warn you against the commission of error. Repentance is also implied.
As long as this dream is one in which reverence is shown, it is propitious. To dream of praying before an altar is an omen of release from pressing worries.
