I've had the same nightmare since my childhood.  I probably have it once or twice/year.  The basic idea is I'm away from home for a long time maybe years.  When I return my fish tank is filthy and I start to clean it.  The fish are still alive and huge!  I'm afraid to put my hand in but I do it anyway.  Last night I had the same dream this time the boys helped me clean the tank and I had no fear. 

I didn't know reoccurring dreams could evolve.  is this the end of the dream? Was it about my boys?
