Dream of killing giant black widow

Hi friends! I had a dream last night that was my usual crazy nonsense dream, but near the end of it my brother and mom were over and holding my son, and a giant black widow was crawling next to them on the couch. I smashed it with a book and it kept coming back up or trying to come back up so I had to hit it 10+ times before it died. For some reason the imagery in it was very disturbing? Like the black widow was huge and looked wrong and alien. I’ve seen mixed opinions on what black widows mean in dreams so thought it would be fun to ask! Thanks
