'X' Berries in dream world?

Question

I've seen on people's share shelf the 'X' berries (those that act like X-attack etc.) like the Apicot, but there is no information on where or when these were released to the dream world. Where would these berries have ORIGINATED from? (I don't want to touch them in case they're bugged in some way/non legit)

Comments

I'm no expert at the Dream World, but according to:
http://www.thonky.com/pokemon-black-white/dream-world-berries/
there are some berries that can be found on other people's share shelves - meaning they don't exactly 'originate' anywhere, and if they do, there origin is unknown.

I'm pretty sure that you can get these berries by participating in tournaments for the GBU (Global Battle Union). They are simply a participation prize, and are not bugged in any way.
