Inner Tube – Dreaming about an inner tube is a symbol of water-based recreational activities. As a flotation device, it also symbolizes our innate fear of water and therefore of mortality. Dreaming that you are floating behind a boat on an inner tube is a symbol of the simultaneous embracing and protecting from death that we experience every time we swim in a deep body of water. The inner tube also symbolizes the wheel, which is itself both a symbol of time and of the journey to accomplish our dreams and ambitions.
