Instance is very similar to example because it actually means the same thing, so instead of using example all the time try using instance because they both might be different words but with same definitions
Instances are dungeons and special areas in World of Warcraft which many copies can exist at once. An instance allows many groups of players to traverse the same geography and battle the same enemies at the same time, without interfering with each other. Instances are accessible by a swirling portal. They may be blocked by a locked door which requires a key.
Instances were made as a way so solve a set of related problems which had become obvious. Everyone wants to slay the hardest monsters and get the best loot, but having the whole server at the very same spot at the same time would've crashed the server.
In World of Warcraft you can find instances such as Naxx and BWL.

Being unable to play a instance (or dungeon) in World Of Warcraft due to too many other instances already being in play.
Most commonly, the player sits outside the dungeon and cries about quitting the game, but for some reason you end up spending hours upon hours waiting until you can get in.
Human Priest: i keep getting "Additional instances cannot be launched, please try again later."
Dwarf Hunter: OMFG THIS IS BULLSHIT I CAN'T BELIEVE I PAY 15 BUCKS A MONTH FOR THIS.
when you're out and about and some girl you may or may not remember from the past comes up to you and is either pregnant or with a child. Then she claims that YOU are the father.
I was in a BW3 restaurant and this short stacked young blonde woman dressed in a black sweather, a short black skirt and black shoes called out my name and she came up to me with a baby boy and his eyes were like mine. Oh no. Who is that girl? Where did I meet her? This is a Billie Jean instance. It's just like the 1983 Michael Jackson hit.
