Dream Symbol
ferris wheel

• Perspective or vision: needing it, wanting it, or having it
  
• Ability to see the "big picture" (the whole situation, problem, environment, strategy, etc.)
• The idea of going around and around, such as circular logic or a feeling of "getting nowhere"
  
• The need for a change of perspective or a change of pace in your life

Also, consider the context and your feelings:

• If you want to get off the ferris wheel but can't, it might mean you're feeling stuck in a seemingly never-ending situation
• If the ferris wheel gets stuck while you're on it, it may represent getting stuck or stranded in real life somehow
• If you want to get onto the ferris wheel but can't, this could represent a need to get some perspective about your life
