Poor BUT necessary?

       Somebody "we" knew reversed the concept of Dreams.  I was always sort of given the impression your brain was, allegedly, replaying/sorting past events.  T B H I remember few Dreams and any I do seem totally unconnected to previous events. 
       The person I have in mind was more of the opinion that Dreams were of a prophetic nature;  I don't know where s/he got the idea and never gave much thought, or credence - until now. 
       I can NOT, for the life of me, remember when - BUT - have a vague recollection of both dreaming the Tropaeolum was still alive, after having checked and of being sure it had died and dreaming I'd checked and been unable to find it.  With me so far?  I'm NOT.
      Anyway - poor though it is, blame forgotten use of, still attached, 600mm Lens.
