The double-decker is a common symbol in dreams and literature. It represents a journey or journey to self-discovery and understanding. The dreamer might see themselves on top of the double-decker, looking down upon everything below them with awe, but also with fear and trepidation.
The idea of a double decker bus is that it is a vehicle that can transport lots of people. The top deck is accessible by the driver and the lower decks are accessible by passengers. The interpretation of this dream is that you are feeling like you have too many people to manage in your life, and you feel like they are taking up all your time.
A double decker in dreams can also symbolize a situation where there are two different sides to something. It may also be used to symbolize the idea of being on top of the world or having more control over your life.
