Dreaming about being fake often represent the superficial or ersatz aspects of life. They can also symbolize our desire to be someone else, or the feeling of being fake in society.
For example, you notice in your own life that you are becoming less reliable and truthful. You start to hold back parts of yourself to get people to like you more or keep them around. Or you are nervous about meeting new people and hope they will like you better if you pretend to be someone else.
Your fears of not being genuine or true to yourself could come from negative messages from other people in your life, or it could be that something has happened in the past that caused this fear of being fake to manifest itself in your dreams.
Lastly, in the modern world where social media is king and the line between what’s real and what’s not is blurred, many people have started to feel fake in their own lives, as if they are always putting up a front to appease others. Some people have even come to believe that most of their friends on social media are actually fakes.
