I don't know about your dream but, I'll confess that I am INSANELY jealous of your perfectly white gray hair!! LOL I started getting some grays at 28 and I can't bear to let my natural color grow out because there are now SO MANY. I'm only 34!
On my mom's side- the women get white streaks at their temples and widow's peak. All perfect... until it all turns this gorgeous silvery white color. But, lucky me- I took after my father's side.. all nonsensical salt and pepper.
As a side note- I keep my hair dark fire engine red! So, I had to reply... LOL (and my favorite animal besides dogs- owls... get outa my head man!! ;-))
