To get what your see in your mind's eye, you will most likely have to add some light, usually from a flash, set pretty low, set for rear-curtain trigger (so the light from the flash comes at the end of the exposure), and off-camera if possible.
You might also try some light painting (using a handheld light like a flashlight and sweep it over a portion of the subject during the exposure.
Very good, that is exactly what I am going to try next! And I have some soft LED Christmas floodlights I am going to try to put into the center of the tree. Wish I would have thought of that before adding all the decorations...
