There's limits to analogies but take a look at a soliton in a wave: https://www.youtube.com/watch?v=909o_kbCdFg https://www.youtube.com/watch?v=909o_kbCdFg Solitons are self re-enforcing wave packets in some medium, where the dispersive effects get canceled out. I like to think of field quanta as being similar at a very high handwavy level. Of course the trick with quanta is only certain energy levels are allowed.
