Hey man I hope you’re better now.
You know what, your experience reminds me of something that happened to me a long time ago, I was once trying to invoke the energy of the 7 archangels through a guided meditation and some prayers, at first everything was fine, normal, I was in a state of deep meditation and Basically what I had to do was imagine the archangels and their color of light and then make some affirmations and when I got to a part where I imagined the archangel Zadkiel (I’m not totally sure since it was many years ago) and his violet light I felt similar to What you mentioned, was a strong pressure on the forehead or third eye and a racing heart, a feeling of panic the further I went the more I felt it, but if I stopped repeating the affirmations I calmed down, anyway despite that I continued forward and finished the meditation, then After that I lay there thinking about what happened but I already felt normal, what I felt was that what happened to me was something similar to reliving a traumatic memory but clearly not from this life.
A long time later I met someone with a lot of knowledge on these topics and a very spiritual person who made me understand that these types of reactions are linked to past lives… many of us, especially spiritual people (or starseeds), work with certain entities or gods multiple times in the past and many times we were killed or punished for those actions and when in this life you reconnect with that entity it is like having flashbacks of that trauma that you cannot understand but your soul can. My point is that you have probably worked with that demon in a past life and things didn’t end well, and when you saw his name or feel his energy you had that kind of reaction, we have done many good and bad things over the centuries. I’m not sure that this is the same thing that happened to you, but it makes a lot of sense from this point of view of reincarnation.
and maybe knowing another possibility of what could have happened to you other than it being an attack can make you feel calmer.
