Again, the spider!
In The Standard Edition of the Complete Psychological Works of Sigmund Freud, by Sigmund Freud and James Strachey (1923, 2014), Freud writes:
According to Abraham (1922) a spider in dreams is a symbol of the mother, but of the phallic mother, of whom we are afraid; so that the fear of spiders expresses dread of mother-incest and horror of the female genitals.The "Abraham" here refers to Karl Abraham, who published a 1922 paper, "The Spider as a Dream Symbol," in which he expresses the view that Freud ascribes to him.
I'm not one to take Freudian symbolism as all that persuasive, but I would expect that identifying a spider as a symbol of female genitalia, if valid, would tend to show up in such psychological systems of symbolism, and we have just that here.
