Defined as a state of unending existence, immortality is something that people wish to obtain. Dreaming that you are immortal symbolizes qualities such as longevity, imperishability, and godlike. You yearn to obtain something that no one was ever able to have. To see that you are immortal in your dream indicates that you are not intimidated by the future or fearful of any adversity that comes your way. You would be able to handle any situation. Seeing yourself imbued with immortality reflects your belief that you are better or of higher status than others.
On the other hand, dreaming that you are immortal represents your unyielding and stationary nature. You do not wish for any changes to your current powerful state to change. In other words, you like things the way they are and do not wish to move anything.Guide and Resources on Immortality in Dreams
