It is widely theorized that communication in dreams is different than that in waking-life, with some researchers going as far to say that it gives the dreamer an understanding of their inner workings. In this way, the dreamer can gain a deeper understanding of themselves and where their unconscious is coming from.
If your dream lacks communication or an audience, you might not be feeling good about yourself right now, and you might be lacking in self-esteem. This isn’t because of anything you did – it’s just how your brain works and it needs to be rewired to help you manage those feelings.
