A dream of you saying no or having someone saying no to you is about boundaries.
The dream can be suggesting that you set boundaries or that you need to open up and be more receptive.
If someone is telling you, “No,” then your dream is trying to get your attention to be aware of the boundaries other people are setting that you may have been ignoring.

We are capable of standing on our own two feet.
