Purple Palm tree in dreams
A tree of warm places — flexibility kept upright under long sun and occasional storm.
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 Palm tree
A palm tree in a dream is the dream's image of upright flexibility in warm conditions. Palms grow tall on slim trunks; they bend in storms instead of breaking. The dream brings the palm when life has been good and easy for a while and the question is whether you can remain yourself when conditions are favourable. A palm in a steady wind is the dream telling you the flexibility is appropriate to the weather. A palm flattened by a hurricane is the dream noting that the same strategy that worked in normal storms is not adequate for the one that has arrived.
