When you look through a kaleidoscope, you see something lovely. But if you shake it up, ruining what's within, and then hold it up to the light, you'll see something new and different, but as lovely.
Life is like a kaleidoscope. It will always show something fresh and lovely after being shaken, but only if we take the time to lift it up to the light and gaze within. The kaleidoscope symbolizes the childlike spirit of humanity.
This tiny toy's many colors and forms will remind people of Mandala flowers (see Mandala) and other things, all of which are very appealing to children's imaginations. A kaleidoscope in a dream might mean that your restrained creativity has been released.
