Flight (escape) dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Martha Clarke
Fleeing signals a desire to evade, if the dreamer herself is the one escaping.
It is possible that, in real life, you are carrying a really heavy responsibility or do not feel capable of solving a particular problem. In addition, if the dreamer witnesses someone else’s flight, the dream reflects a tricky situation: the protagonist knows of a secret truth and fears the consequences that may entail its disclosure.
