Self-empowerment, or a desire for it.
The experience of your "true" state of being, without limiting beliefs or self-judgments
The acknowledgement of your ability to do what makes you happy without worrying about what other people think
Dreaming that you are invincible against harmful people can represent:
Deciding to not let other people's judgments "get to you" in real life
Feeling too many demands or attacks on you or your time, energy, autonomy, privacy, etc.
