Whatever was launched has entered into a new course of action
In the sense of setting a boat afloat, a launch picks up the spiritual significance of a boat and also suggests some kind of initiation or the beginning of a process.
Psychological / emotional perspective: Launching is associated with throwing – particularly a lance – and, therefore, emotionally represents perhaps an initial enthusiasm or enjoyment.
Material aspects: Launching a project in a dream suggests the beginning of an exciting time.
A launch was initially a smaller boat for use on a larger one, so therefore can suggest an offshoot of a task or idea.
To dream of a ship launching from the wharf or pier implies the birth of an exciting project or news of an actual pregnancy.
To dream that you are attending a rocket launch indicates a dream coming true and cautions dedication and focus to keep grounded.
To be at your own book launch may symbolize the beginning of a new chapter in your career.
Dreams of a launch symbolize that you are ready for take off; a public entrée for your career and/or relationship. Prepare for a blast off into exposure and recognition.
