I have a dream place that has a massive spiralling glass building with a roller coaster in it.
Dreams about buildings usually represent the dreamer's inner self and their personal development. The spiralling glass building in your dream can signify a journey of self-discovery or personal growth. The roller coaster within the building can represent the emotional ups and downs you experience on this journey.
The size and transparency of the building suggests that you have a clear understanding of your goals and aspirations. You have a strong desire to experience the highs and lows of life to better understand and develop your character.
Overall, this dream may indicate that you are ready to take on new challenges in your life, especially those that may cause you some initial discomfort or fear, but ultimately lead to personal growth.
