Purple Marlin in dreams
A large, fighting ocean fish — strength that takes the longest line to land.
How purple changes the reading
Purple colour places the symbol between hot and cool — a reading that has both calm and intensity at once. The dream often uses purple for symbols that do not fit the usual categories cleanly. Take the reading more seriously than you would otherwise; the colour is asking you to.
The base reading of Marlin
A marlin in a dream is the dream's image of a goal that, once you hook it, will fight for hours. Marlins are not given up easily; the contest is famously long and physical. The dream brings the fish when an ambition you have been chasing has finally taken the bait, and the next phase is endurance, not pursuit. A marlin still on the line is the dream telling you the work is real and worth the strain. A marlin breaking off is the dream marking that you spent the first energy on the chase and did not save enough for the fight.
