I agree that it could be one of the sigils of Lilith given that the image resembles what others have seen or drawn. Feeling a bit weird here as I type just getting a little deja vu, not that I have seen the image before, but weird.
I would suggest keeping the image in the way you have it drawn with the 7 points if in fact that’s the way you saw or how it was drawn out for you under possession. Whether it is 7 points or 11 doesn’t matter at this time. These are just signs or clues pointing to what can be expected in the future, in a week, a month or even years from now. Maybe some future qliphothic workings with Lilith or someone else I don’t know.
I won’t mix and match sigils and tie a name to the image since I don’t believe these deities make mistakes when drawing things out. But just for reference, the spider to me resembles the venomous black widow an aspect of the deities nature on the web/tree of life/death. The 7 points could be aspects or masks of the deity and/or its entourage and maybe even corresponding to the 7 chakras. I’m just throwing the chakras out there because you shouldn’t just discard the 7 pointed symbolism the way it has been drawn out for you. I wouldn’t necessarily align the 7 points with the planets since it won’t make any sense with the other symbols found in the image. The Tridents can symbolize its intensity in power and the Crescents are the energies it aligns itself with. I’m stating this because many of these symbols can be found with other systems but basically pointing towards left-hand path type of workings to be done!
This was probably useless information but maybe someone else can find something in it.
