Marjorie This may beof interest to you---- several years before my PD was dx the whole family got a terrible flu Iwas sick - really bad for 4-5 days- then I noticed that I felt better and I looked down at my toes and saw that I was in my bed with my scarlet blanket I had been under that blanket for days and I had seen it just in shades of grey. and everything else had been grey too. and now every thing was it's real colour. quite suddenly. I have no explanation and it has never happened again Anne
