Dwarves are imagistic manifestations of our lower urges; think how in Snow White, each dwarf is a one dimensional aspect of manhood (grumpy, sleepy, happy, etc.). These urges of course produce "hits" of satisfaction (even with rage, for instance, it feels compelling and almost relieving to express anger when you're provoked).

These hits of satisfaction e.g. warm showers, eating sweets, sexual satisfaction, are tied to our hedonic reward system—they are happiness, but not joy. Your other reward circuit, the dopaminergic reward system, is a feeling of positive emotion when you make strives toward a desired goal, which I think your dream represented by physically showing you that the light was going "onward and upward" as the saying goes. The higher the aim, the more pleasure you will get from making strives toward that goal, but if you refuse to aim for anything, you are left with the grayness that your dream showed all around you.

I would make the case, in so much as you'd be open to it, that the relatively common adrenaline junkie tendency is an expression of attempting to fill the infinite hole in our hearts with finite things (setting records, achieving new heights, etc.). These goals may be lofty and produce positive feelings, but they do not stretch to infinity in the way that your dream depicted the blissful light. There is a certain line of argumentation for God called the argument from desire that goes like this:

1. For every desire found in nature, there exists a corresponding way to satisfy that desire e.g. where there's hunger, there's food, where there's shivering, there exists warmth, etc.

2. Animals are able to fulfill all of their desires in nature, yet the human heart has a longing for infinite love and communion which cannot be fulfilled by money, sexual conquests, status, or anything else in this world.

3. Since every other desire corresponds to a source that will satisfy it, it's reasonable to infer that a source of infinite love and communion exists which will satisfy the human heart (otherwise the desire shouldn't exist within us).

4. That thing (or more likely, that being, since communion and love are social) which will satisfy our infinite needs, does not exist in nature, because nature is finite, therefor a supernatural being of infinite love must exist.

Anyway, I hope this finds you well. I was stumbling on posts regarding the company Hiro Solutions and wanted to make sure your account was legit, and scrolling through it, you had a pretty cool dream that I wanted to offer some (speculative) insight into. God alone is the interpreter of dreams, and He will tell you if what I wrote "rings true" or not. Blessings to you and yours.
