A process or activity ending can represent an actual, feared, expected, or imagined situation where something ends. Consider the context, such as whether this was expected or a surprise, who or what was involved, and how you felt about what happened in the dream.
If you are the one ending the activity, consider your feelings and reasons why. It could mean you want to end something, or feel you need to or should, or feel the activity has run its course or arrived at its natural end.
