Significance of potion in cave - Weasley's day dream potion?

Has anyone considered the significance of the defenses in the cave? In 
particular the potion seems to cause DD to dream - it reminded me of 
the Weasley twins' Day Dream Potion (except this would be a nightmare 
version).... perhaps cause the person to dream his/her worst nightmare 
in addition to the physical damage it works


Any thoughts on the significance? If any?
