Seems fine. What were you trying to do exactly? As the mage, you need to be clear what your intention is so you can control and understand the results. Vague intentions leads to vague results.
Eh, without having seen the video, that sounds kind of silly. I’d suggest you rely on your intuition and do not let random youtubers tell you what to think based on their arbitrary opinions - they probably work great for them, but magick is first and foremost highly personal. Trust yourself, and pretty much nobody else unless you verify their UPG (unverified personal gnosis) also works for you…
I’m not really seeing sign of anything yet… did you ask for a sign? If so what did you ask the sign to be about? Like, “Lucifer, please give me a sign that you are interested in working with me.” did you say anything like that so that anything happening would be in response to it?
The sensations are likely to be your internal energy (which I call qi) moving, which is common as you start meditating.
Out of curiosity, in your intro you said:
So why the sudden switch to Lucifer and the religion of demonolatry, which have has nothing to do with these things?
This is all you really need.
