Dream about sea lion points to your productivity. You are getting a handle on a problem. You or someone is up to some trick. This is a signal for industry and hard work. You are experiencing feelings of self-doubt.
Sea lion dream signals acceptance of yourself. You are struggling with gender roles and what is acceptable. You have lost faith and belief in yourself. It is a symbol for the roles you play in your life and the various acts and personas you put on. Somebody may be showing you the way to solving a problem in your life.
If you dreamt about sea lion:
Some of them you may enjoy, but others will leave you yawning. You might like the discussions you have with your partner, which could be quite revealing, but you may dislike being asked to change your nature, or be different than the way you are. Think carefully before you answer. You could be getting yourself into some kind of verbal tangle.
