A bubble being spherical suggests perfection, in this case temporary, and, therefore, represents the illusory elements of everyday life. More specifically, it suggests the daydream in that it comes and goes. Bubbles as beautiful but fragile objects remind us of the transitory nature of human existence - that nothing is permanent. We may dream of bubbles as part of our need to have fun in a childlike way. We often become aware of the temporary nature of happiness and our need for illusion.
