Is it normal to collect blind bag/box toys as an adult?

Like shopkins (tiny little "cute" figures that are collectibles geared towards children around 6 years old) and vinyl figures like the walking dead, doctor who, etc? I know the vinyl figures aren't so bad as they're actually geared towards people 16+ but the tiny toys some of which are mini disney figurines is crazy weird, right?

I'm an adult female and I can't help it...is this pretty bad or what? I've always been into kawaii stuff (cute japanese anything) and still buy hello kitty items when i see them because i can't help myself!
