Some really weird dream/nightmare about a spider

vague recollections - some guy used to be with a woman but broken up or in the process, now. The woman gave birth to a child but the child’s form had been a mystery... the grandmother literally starts transforming into a “spider” symbolically and otherwise and daughter realizes that is part of who she is. The child is a literal spider as well. The guy doesn’t want to entirely abandon his family but he also has some kind of entanglement with “me.” The characters are actors from a tv show I just watched but despite their faces the aforementioned is how they feel like to me. The whole time everything is shrouded in complete secrecy, dark. I feel jealous. For some reason I have to meet him in secrecy or else people will try to stop us. It’s all so he could be with the weird spider family. He is put off by it too - but it’s his child so he has strong attachments. Literally “spinning a web”? Manipulating him. I have a sense I will eventually lose him because of these forces outside my control.
