Go Down the Rabbit Hole 

To follow a thread or a lead that branches off from your initial objective, then (often) doing that repeatedly to get your self lost and/or completely off topic. This is based on the fact that Rabbit Holes (or "warrens") are often interconnected dens and tunnels with no apparent pattern to them, but in which one would surely get lost if followed impulsively. (See also: lost in a maze, or trapped in a labyrinth.) (This predates Lewis Carrol, whose meandering fantasies are very much like a random stream-of-consciousness exercise.)

I started researching Electric Cars, but started to Go Down the Rabbit Hole, following stories about Nikola Tesla, which eventually lead me to a list of David Bowie's movie roles.

Wikipedia Rabbit Hole 

It's not just a hole. It's a rabbit hole, akin to the one Alice fell down to Wonderland.

I enjoy falling down Wikipedia rabbit holes because I never know where I may end up.

White Rabbit Hole

A mysterious inner path that leads to an awakening and understanding that things are not as they seem. The "White Rabbit" is symbolic of "inner understanding" that a greater reality exists and requires immediate refocus of ones attention. The alligory is based on character from the story "Alice in Wonderland" who is "Late for a Very Important Date!". "The Hole" is the "matrix of choices and information". It is an oft bizarre, confusing and uncertain path .. which can lead to either great wisdom OR potential folly depending on the choices made.

"That Speaker was a "WHITE RABBIT HOLE" of information."
"Welcome Neo, you have found the White Rabbit Hole wherein you might find the truth regarding the MATRIX!

Go Down the Rabbit Hole 

In addition (or exception) to the chaos and confusion mentioned in the previous definition, there is adventure, discovery, and maybe even some excitement 'down the rabbit hole.' The unknown is 'down the rabbit hole,' and may also be present in the hallucinogenic experience mentioned in the same previous definition.

In the movie, 'The Matrix,' the pill chosen could perpetuate the myth or uncover the truth, a truth that was not as pleasurable, but was definitely exciting. Alice probably liked the fantasy her choices displayed rather than the reality exposed by a similar choice in, "The Matrix."

Alice wouldn't have chosen to go down the rabbit hole if she thought it might not be fun.
