Please help me understand what's happened to me. Earlier, I was praying to my divine mother, doing some pranayama and the Klim protection mantra from your youtube channel, and then meditating on Arcanum 5 for a little over an hour altogether. Afterwards I crawled back into bed lying on my side and started to fall sleep, when all of a sudden I felt my neck being squeezed on both sides. I WAS ALONE in my room. It was not a chokehold, so my throat was clear. I felt something attaching itself on my back and squeezing my neck. It was clear as living daylights that there was something alive but not from this world holding onto me. I was scared but remained still. I forced my eyes to open slightly but my physical eyes did not open and yet I saw a little bit of my room in a different color. I saw nothing in front of me. At this point, I forced myself to get up and found myself sitting on my bed. I looked behind me and saw nothing there.
Is this Karma? What just happened to me and how can I prevent this from happening again? I was aware of it this time. How do I know if it's been happening to me all along without me being aware of it until now?
