i've met various authors if that counts, like ellen hopkins, charles benoit, and suzanne young.
if youtubers count, i'd want to meet jacksepticeye, dan and phil, pewdiepie, shane dawson, drew monson, and idubbbz as well as markiplier and crankgameplays! lots of people o-o
My dream would be to meet James Hetfield, and after my most recent dream about Metallica, I feel like it's something I 'should' do.
I didn't meet and I don't really feel the need to meet anyone in particular, but If I had to choose it would be football players from my favorite team.
