The first thing that stands out to me is the endless rooms you encountered, all connected directly to each other. This could symbolize the vastness of your subconscious mind, with each room representing a different aspect of your psyche. The fact that there were no hallways or mezzanines suggests that there is a direct connection between all of these different parts of yourself and that you are exploring them all without any barriers or limitations.
The different shapes of the rooms could also be significant. The rectangular rooms may represent stability and structure, while the half-triangle half-square room could symbolize a sense of incompleteness or instability. The decagon-shaped room may represent a sense of wholeness or completeness, as the number ten is often associated with completion in numerology.
The people you encountered in the dream may also hold symbolic meaning. The elderly woman with jet black hair in curls may represent wisdom or the feminine aspect of yourself. The fact that she was spinning a wheel of multi-colored lights suggests that she may be connected to your creative or spiritual side.
When you told her that you were lost and searching for something, it could symbolize a deeper sense of purpose or meaning that you are searching for in your waking life. The fact that you couldn't quite put it into words may indicate that it is something that is deeply buried in your subconscious mind.
The vortex of concentric rings of light that you saw after practicing the breathing technique and yoga mudra could represent a spiritual awakening or a deepening of your intuition. The sphere glowing blue and green cube of light may represent a balance between your logical mind (the cube) and your emotions (the sphere).
The words "peace" and "unity" that came to mind could represent a desire for harmony and a sense of interconnectedness with others.
Finally, the advice that the elderly woman gave you about which doors to take and which to avoid could symbolize the need to trust your intuition and make choices that align with your innermost desires and values.
It seems to me that your dream is pointing towards a deepening of your spiritual and intuitive side, as well as a search for greater meaning and purpose in your waking life. I hope this interpretation helps you gain some insight into the symbolic meaning of your dream.
I needs to dwell some more on the wheels of light etc. so I gp to the second part now.your analysis of this dream is extremely interesting. i had never thought of it in those terms. however you may be right. i knew i had come there in search of something, i did not know what(or maybe i really did. i just didn't have a name for it) but the solution is stop the internal dialogue ,to borrow an expression from don juan. drop the conscious analytical mind and listen to your own feelings and thoughts. what i actually did do in the dream. and then i got some answers. it would be interesting to know your view on the wheel of light. or the blue sphere of light,and green square of light behind it. i should have the second part of this posted pretty soon.
