Energy focus in a chart
Sita,
While I have not heard the term "dumps out" used before, I have heard and use the word "focus" to describe the effect of aspect patterns and chart patterns in a chart. In your chart you have an Easy Opposition focused on Sagittarius (expansion, also wisdom) modifying Neptune (spirituality, also confusion) focused in the 10th house (duty). This indicates there is a focus on understanding your spiritual duty in the world, but also that this search for a spiritual duty could become confusing.
I also read this from a Google search containing more information about the Easy Opposition:
...I was just reading though my mom's ancient and well-travelled copy of Alan Oken's Complete Astrology, and in it Oken mentions an aspect configuration called an "Easy Opposition." This is when a planet trines one end of an opposition and sextiles the other...
An entire chart can have a focus also. For example, you have Locomotive chart. According to Tracy Marks, the author of The Art of Chart Interpretation:
Locomotive pattern...All planets fall within 240 degrees (or a maximum of 250 degrees) with no more than two houses or 60 degrees empty within the occupied area, and with a trine bridging the
unoccupied area...energetic, self-driving, determined individual who single-mindedly focuses upon achieving...[their] purpose, which is generally indicated by the midpoint of the empty trine...(the first [planet] to have crossed the ascendant, moving clockwise) is the engine; its sign and house position indicates the energy which fuels...[their] drive to incorporate the midpoint of the empty trine into...[their] life.
So there is a focus in your chart on the midpoint between Neptune at 18 Sagittarius and Mercury at 20 Aries (the midpoint of the empty trine - the trine with no planets between the trine). This places the midpoint at about 18 degrees Aquarius, in the 1rst house (being, also action). So there is an focus on understanding who you are using Neptune (the first planet to have crossed your Ascendant moving clockwise) and driven by education and duty (Sagittarius and 10th house).
This focus of the locomotive chart reinforces the focus already mentioned of the Easy Opposition. So a "life focus" is starting to become apparent: involving spirituality, maybe confusion, and responsibility.
Focusing,
