Below are a few dreams and visions that myself and others have had about Skadhi, with associated Personal Gnosis, where applicable.
The first vivid vision I had of Skadhi was at a Norse sweat at FreeSpirit, in June of 1999. It began with three bluish-white Isa runes, appearing in the middle of a valknut. The triangles of the valknut break apart and distend, moving outwards, leaving the Isa runes in the middle. Dimly aware that I am having a vision, I call to mind the image of a snow owl, since that is a creature I associate with Skadhi. However, after I bring the image to mind, I lose control of it. My perspective zooms in on the amber eyes of the owl, and I see that there are fires burning behind them, I'm soon so close I'm nearly inside the eyes, and I can see that in the fire is a man, strapped to a rock, writhing. It is Loki, and he is screaming. The vision ends.
What do I think this means? Well, before I was a Skadhimadhr, Odin was the deity I worked with closely (though I was never dedicated to him). The valknuts breaking apart and making way for the Isa runes in the middle seem to represent Odin giving way to Skadhi in my life. As for the image behind the owl's eyes? My own UPG is that Skadhi hates Loki. Almost uncontrollably.
Vision two took place during a guided meditation in December of 1999 (a day or two before Yule). I'm walking up the path through the woods where I hunt, towards the top of the mountain. I get to a thick circle of trees, so thick that the trunks have grown together to form a nearly complete circle. I enter the circle of trees. I wait for a while, not really knowing what to expect, and eventually a campfire appears in the middle of the circle. I look behind it, and see several indistinct images. Suddenly, there is a knife in my hands. I plunge it into the earth, and drag the blade towards me, gouging a line in the soil. It occurs to me that I have drawn an Isa rune. I do it two more times (in the now familiar pattern that appeared to me in the previous vision), and it starts to snow. Hard. Pulsing, living sheets of snow, falling so quickly and strongly that within seconds it is up to my ankles, and I need to leave the circle of trees or be drowned in it. I leave the circle, and I see a pair of snowshoes outside. I wade through the now nearly hip-deep snow, and and put them on. I call out for Skadhi. I see her off in the distance, over the mountains, but quickly, we are close together, and I'm pretty much staring into her knee. She's so very tall. As soon as I think this, she shrinks in size, and I can see that her face is a shifting pattern of different drawings I have done of her. She silently hands me a bow, and three arrows, and points behind me. I look over my shoulder, and see only the mountain, the trees growing on it, and the sky. I shoot the first arrow into the sky, over the forest and the top of the mountain, and I watch it disappear into the distance. I take the second arrow, draw back the bowstring, and let it fly as well. Over the trees, out towards the horizon it goes, as well. I draw back the bowstring a third time, and aim for the sky again. Just before letting it go again, I instinctively lower my aim, and fire the arrow directly into the center of a large tree. I get the feeling something significant just happened. I snowshoe up to the tree, and I see that its been split lengthwise. I tear the tree open, and I find something inside that is mine, an essential, formless part of me. I'm trying to figure out how to get it back inside of me where it belongs (I give a passing thought to opening myself up with the knife) and eventually just push it through my skin and ribs and into my chest. I turn around, and Skadhi is still there. We have a short conversation, and the vision ends after we have finished speaking.
As for what this means? Well, most of it is personal, but it cemented in my mind the triple isa bind-rune, which I now use when I need to invoke or call her.
