Dreaming about being lost tells you that you have lost direction in your life, or that you are no longer clear on your original purpose. Another explanation is that you are concerned or unsure about your life path that you are walking at this point in your life.
Another explanation of this dream or vision is that you are getting used to a new situation where different rules apply. An alternative explanation for being lost is that you are looking for opportunities that can present themselves and what the consequences can be if you start making these choices in your life.
Dreams about being lost represent the inner feeling, but also the fear of being literally lost in life and/or the situation you are in. It is more than just not seeing the forest for the trees. Losing yourself, soul stirrings, depression, burnout, having no control and so on.
