A dream with an obvious interpretation

I was watching 24 Hours in Emergency last night on SBS, due to a lack of anything else to watch.

As far as reality medical TV shows go, it seems reasonably well done, if (naturally), intrusive of privacy.  But I was interested mainly in the story of a guy who in hospital after falling 40 feet from a tree, onto concrete, but lived to tell the tale.

In talking about his life generally, he explained that his mother had died when he was young - I forget the age, but it might have been around  3-5, I think, because he indicated he didn't really understand what was going on when the police arrived and the rest of the family started crying.  She had been killed by a drunk driver when at a petrol station.  (He said she was standing in front of her own car, and the drunk driver's car rear ended the car and it ran her down.)

Anyway, the son (now in his 20's?) said that a year after his Mum died, he started having recurring nightmares in which a dump truck would unload on - or run over? - a flower, and he would wake up feeling really devastated.

That seems to me to be an unusually clear case of a dream which seems to validate either Freudian or Jungian dream analysis as meaningful.  

I don't mean that I am completely cynical of dream analysis as an exercise - but cases where the dream has such an obvious hidden meaning, and one where it would seem the mind is sort of protecting itself from a full imagining of what happened,  I would still think are a bit unusual.
