Vision: Watching someone rollerblading: you are too slow lately—others have passed you by.
If you are rollerblading: you are working on an important project and would like to get it over with—don’t be in a hurry, that won’t work. Looking at rollerblades: you must act fast.
Depth Psychology: Depending upon the rest of the images, the dream could have either meaning—slow down or get moving because others might overtake you.
