The meaning of velocity in dream | Dream Interpretation
(see Bus, Car, Travel)
Moving slowly in a dream may reflect taking your time and considering each step necessary for success. Alternatively, it can indicate procrastination or delays that may or may not be of your own doing.
Rapid movement represents hasty actions which may not have been thoroughly thought out. This can also reflect that you are moving through life so quickly and busily that you never stop to smell the roses.
Dream sequences that go in very slow motion are usually replays of something that’s happened so that you can examine the details more closely and from an alternative perspective.
