I had a significant experience last winter solstice in which I encountered an entity that wasn't part of the lexicon, but rather one of Egypt of whom I had no prior knowledge. When I looked it up on the internet following the experience, it looked identical to what I had seen, and there were further interesting implications of the encounter with this specific entity. I talk about it
here. I talk about another experience where I encountered entities, and it wasn't until over half a year later in obscure reading that I read the exact description of
my experience though a quotation of Hebrew mysticism (which I'm likewise pretty unfamiliar with).

"The Mighty One appears, the horizon shines. Atum appears on the smell of his censing, the Sunshine- god has risen in the sky, the Mansion of the pyramidion is in joy and all its inmates are assembled, a voice calls out within the shrine, shouting reverberates around the Netherworld." - Egyptian Book of the Dead
