Herakles / Hercules dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Theresa Cheung
The ancient hero Herakles represents the strengths and weaknesses of brute force. Depending on your circumstances in waking life, Herakles—or another aggressive archetype, Ares or Mars, the ancient gods of war—may be represented in dreams by any figure that is attacking you or someone else.
If this is the case it may suggest a need to be more forceful and take action in waking life. Alternatively it may also indicate the need for a quieter, more thoughtful approach.
