Does this dream mean anything or was it just random?

First of all one needs to understand that dreams are symbolic representation of our inner self since they are reflection of our mind which is a store house of data collected over a period of time. The mind analyses and projects possible solutions to our problems / tensions in the form of dreams. Swimming Pool represents feelings / desires, wall represents present situation which in this case is having a difficult path / solution, height represents goals, fear represents inner inability. Therefore, the dream indicates that the desires housed in the mind have a difficult solution which can only be overcome by inner strength and confidence. BOL (Best of Luck ).
