Dream plan 

A compound word that describes a future journey that recognises the similarities between dreaming and planning to achieve a mutually desired outcome.

When the concepts of dreaming and planning come together, the resulting dream plan is formed.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
