I had spent over a decade with kundalini, chakra work, pranyama, gematria, magick from various systems, shamamism, occultism, tarot and divination etc. Since a young age.
My innate drive was toward lycanthropy. I had researched and employed countless methods using myself as a guinea pig. From sigil magick, reconstructing old riruals, shamanism+invocation, pacts, Goetic entities and Djinn, cursed objects, you get the picture.
My initial encounter with seeing my body shift in some manner was around age 16. Prior to that I had experiences of a wolf spirit and an young native girl dressed in ceremonial garb. Her eyes were of all colors and none. South American looking.
Month later. Restless energy, burning from inside out. Feeling of being watched over course of three days. Third day get on all fours. Hearing becomes amazing, can hear insects in grass, can hear people and electrical devices in building and wind through every tree and bush. See color dim and purple and green swirl in my vision in front. Then pain in face and back. Raise arm up and see energetic layers, see black form around limb. Limb is clawed.
Dialog pours out of my mouth "My will made manifest, my sovereignty over the earth" and more I have little to no recollection of. Pain reaches intolerable levels like I am being pulled apart. Bkackout.
Upon consciousness sit straight up and babble incoherently. Can't talk for half hour. Go to mirror in bathroom to examine self. Back has stripes of fresh horizontal stretch marks in spine crevise from upper mid to tail bone. Vivid and red. They scarred under skin later and were white. Feels like ripples, feels strange. Faded a little. When people see my back they think someone hurt me.
That is tl;dr.
Occasionally blackouts and memories once in a grand while. My research is now in speculating if I can go all the way permanently. Marks confirmed physical phenomenon. Other things too.
Might need privacy and to allow energy to build up.
