A person can have a phobic reaction to anything, and as a result there are some very colourful and interesting phobic conditions, including
nephophobia (fear of clouds), aulophobia (fear of flutes), to name a few.
For another example of meaning-based pseudo-paradigm, I would like to give the following X -- X-phobia pairs: (7) X X-phobia air anemophobia cats ailurophobia, felinophobia, galeophobia clouds
nephophobia corpses necrophobia fish ichthyophobia
