If in a dream you skate on roller-skaters, then in reality you seek to be in time as much as possible, to enjoy life to the full. If dreamed you that, having dispersed, you did not keep on rollers, then such dream should be apprehended as caution. Perhaps, you too scatter the forces. To watch how others skate on roller-skaters, means that you stand on a side of acceptance of some crucial decision.
Be sure and keep any other thoughts out of your mind before drifting to sleep as a cluttered mind can decrease the chances that you will remember your dreams upon waking. Also, focusing on remembering your dreams upon waking in the morning is another very important thing. This sounds very easy, but is often hard for some to do.
