To see a white swan in your dream symbolises grace, purity, beauty, dignity, wealth and prestige. Something or someone that may initially be unappealing can turn out to be quite attractive. It is important not to prejudge a situation or person based on the surface.

To see a black swan in your dream signifies mystery and the unknown. It represents something that is alluring, yet forbidden. 

To dream that you are flying on a swan’s back over a rough ocean implies that you are dealing with some emotional issue as graceful as you can.
