I was running away from evil creatures and was hiding inside a school from them. But in real life I finished school long ago
Dreams about being pursued by evil creatures often symbolize feelings of fear, anxiety, or a sense of danger in your waking life. The fact that you were hiding inside a school suggests that you may be seeking refuge in a place of safety and security. It's possible that this dream is related to a challenge or problem that you are currently facing, and you may be feeling overwhelmed or uncertain about how to deal with it.
Additionally, the fact that you have finished school may suggest that this challenge or problem is related to something in your past that you thought you had already overcome. Perhaps there is an unresolved issue or past trauma that is resurfacing and causing anxiety in your current life.
Overall, this dream may be a reminder to confront your fears and face any challenges or issues head-on, rather than running away or seeking refuge in the familiar past.
