A dream involving a stowaway typically symbolizes hidden aspects or unacknowledged parts of oneself. Just as a stowaway sneaks onto a ship or vehicle without permission, this dream suggests that there may be a part of your personality, emotions, or desires that you have been suppressing or neglecting. This dream may be urging you to explore these hidden aspects and to give them the attention they deserve. Alternatively, it could signify feelings of guilt, deceit, or fear of being discovered. Consider the context and emotions within the dream to understand the specific message behind the stowaway imagery.
