long time since we heard from South London, seems like you are doing well.
Vivid dreams is reported numerous times at the board; at some stage in Iodine supplementation.
Reason why? I dont know but I guess it may have something to do with the pineal gland detoxing from fluoride and start waking up from its cinderella sleep :-)
I would take it as a positive sign. I used to interpret my dreams at one stage, they were always very accurate.
