It means “Transformation” from one phase to another in life, a change in short. It also indicates different things… depending on what it’s laying by.
If it’s laying by a Court Card, usually the Minor Arcana, it can mean literal death… depends on the other cards around it, also if you have allot of Major Arcana cards… this indicates change (even without the death card).
In Astrology the Death Card rules Scorpio.
It simply means that one chapter is ending (possibly dramatically) and another one will soon begin. It does NOT mean that you or someone else will die soon.
It means change.
