Dreams involving deceased loved ones, especially parents, can be profoundly emotional and often carry significant meaning. Seeing your mother walking towards you through lavender may symbolize peace, spirituality, and healing, as lavender is often associated with calmness and tranquility. The act of explaining that you were on the dream plane suggests an awareness of the dream state and possibly a desire to connect with her spirit.

The transformation of your mother into a smaller form that you carry like a child could symbolize a nurturing aspect of your relationship, perhaps indicating a shift in how you perceive her role in your life. It may also reflect your feelings of needing to protect or care for the memories of your mother as you process your grief.

The deep purple eyes and the appearance of the word "Infinity" can signify a deep, spiritual connection and love that transcends time and space. Purple often represents spirituality and intuition, while the concept of infinity suggests that your bond with her remains eternal, regardless of physical absence.

Overall, this dream may be encouraging you to embrace your memories of her and to find comfort in the idea that your connection continues on a spiritual level. It may also be a reminder to nurture both yourself and the legacy she left behind.
