Interesting dream

Something you're working on secretly: therapy? sorting out feelings/experiences?

Perhaps you have a worry that letting certain things out might be harmful or poisonous to others. Things that need to be kept hidden, you feel, and carefully kept. You cannot throw it away - perhaps because it's simply part of yourself as Thunder Bow mentioned, or perhaps because it gives you power by keeping it.

I would look at how you felt about keeping it. Sentimental? Like you had a secret weapon? Frightened? Serious? Protective?
