(Casket; Coffin; Mummy case) A dead person or a mummy inside a sarcophagus in a dream represents unlawful money.
If the coffin is empty in the dream, then it represents a house of evil, or an evil person who is sought by people of the same trade. (Also see Coffin)
1- A sarcophagus is similar to a tomb, but is much more of a memorial, marking how important the occupant is or was.
To dream of such an edifice is to recognise the importance of death and the rites of passage associated with it.
2- When we come to an important change in our lives we may wish to mark the passage or transition in some way. We have a need to have other people recognise or appreciate our efforts.
A sarcophagus would indicate that there is a good deal of ego still to be dealt with within as.
3- Spiritually, death indicates both a change of state and a change of status and a sarcophagus is a symbol of such change.
