What does I shrink smaller every time I take a bath Mean?

The phrase "I shrink smaller every time I take a bath" can be interpreted metaphorically, suggesting a feeling of vulnerability or a loss of self. It may imply that the speaker feels less significant or more diminished with each experience of introspection or self-reflection, much like how objects can lose size or integrity when exposed to water. Alternatively, it could be a playful reference to the way certain materials, like soap, can dissolve or change form in water.
