As mentioned in a sibling thread, the real "dark night" is something that happens only after one is deep enough in the development of contemplation - both the Christian and Buddhist tradition are very clear about this. In fact, that's the reason it's so insidious: many inexperienced meditators get as far enough as reaching a stage of insight that subjectively feels a lot like the common folk trope of "sudden enlightenment". But the "dark night" comes right after that stage, and then they don't know that they're supposed to meditate more and look for the way out (through the insight of equanimity). It's a very understandable mistake, which is why it makes sense to warn about it.
