Down the rabbit hole意思

"Down the rabbit hole" is an English idiom that is used to describe a situation that leads to a strange or unexpected series of events, often involving a lot of exploration or discovery. The phrase is taken from the book "Alice's Adventures in Wonderland" by Lewis Carroll, in which the character Alice follows a white rabbit down a rabbit hole and finds herself in a bizarre and nonsensical world.

In contemporary use, "down the rabbit hole" is often used to refer to a situation where one becomes deeply involved in or obsessed with something, often to the point where it becomes difficult to stop or to see the original purpose or goal clearly. It can also be used to describe a situation that is confusing or unpredictable, where the more one tries to understand it, the more complicated it becomes.
