I’m not going to pretend that I know what your dream was about.
I’ll just discuss what some of the imagery and symbols remind me of or bring to mind.
The 9th house or Sagittarius is about travel and the quest for knowledge. You choose double 9.
9 is also the number of months in the gestation of a human baby.
9 is also considered the number of completion. It’s the largest single digit numeral. After 9, a new numeric cycle begins, same with 99, 999, and so on.
89 being next to 99 is an evocative image. It’s fun to think of what your mind might have been expressing with that one.
99 - the number you choose feels like you may be indicating that you are ready to cross a transition point and evolve to a higher level. Graduating from the current level and becoming like a baby again on a new and more advanced level.
Fitting that your mother, symbol of nurturing care and guidance presented you with a special key. A key that not only opens doors but also opens relationships (greeting card) and ensures auspicious opportunities.
Marked with the seal of the trident. And note that the Trident on the card is itself opening a sphere. That sphere can be a world, a planet, an egg, a point of view, a mind, or a perspective. The trident on the key card is itself a key. And a powerful one. A symbol of rulership, dominion and power.
Neptune rules the seas, the waters. These are the heart, the emotions, and the passions. In mastering the rhythms of the heart, the ways to wisdom are opened.
This may be the next level to which you are traveling.
The card marks you as a ‘chosen one’. (i.e., one who has embraced his hero’s journey). Though you are beginning a vulnerable stage at the start of developing new capacities, you are smiled upon and blessed by the forces of nurture and care. Destined for great things.
In acknowledging your connection to your past, you are opened to receiving blessings from the past, and these protect you on this next phase of your journey.
The trident protects you. It also awaits you. At the beginning of this next phase, it is a mysterious symbol placed protectively above you by ‘ancestors’. But at the fruition of that next stage, the trident of heart-wisdom awaits you as your own, to be wielded and applied with mastery.
You are ready for this next phase of journeying. Embracing the way of Sagittarius, you are optimistic, open, and motivated to learn and to apply what you will learn.
Wish you happy traveling and inspired learning and growth!
