Alice Liddell (c.1848 - November 1871) in 1865 would go down a rabbit hole that was a portal to another dimension known as Wonderland. In the land she spent what she believed was a very long day in Wonderland. In reality she had been gone for months and was discovered wet and miles away from "the rabbit hole".
Alice would go back to Wonderland by means of a mirror two years later. This time her stay in Wonderland was considerably longer in her mind, but in reality she was only gone for seconds. This trip to Wonderland unfortunately reversed her organs and caused her to be unable to consume food again, leading her to was away from starvation.
Alice's journey to Wonderland would later be followed by an expedition led by Eric Bellman, which also shared a similar tragic fate as Alice's.
In 1969, Mina Murray sees Alice in a drug-induced hallucination, esposing her breasts and eating cake.
Alice Liddell is the protagonist of the novels Alice's Adventures in Wonderland and Through the Looking-Glass and What Alice Found There.
Lewis Carroll's books were purportedly tales that were told the Liddell girls, though Alice Liddell asked that the story be written down. Alice in the novels has no last name, and she also does not die because of traveling to Wonderland.
Also to note, Alan Moore featured a version of Alice (surname: Fairchild) as a central character in the erotic graphic novel Lost Girls, in which she describes her sexual experiences to Dorothy from The Wonderful Wizard of Oz and Wendy from Peter Pan.
