Did I just play a grandmaster caliber game against Magnus Carlsen?

So I'm pretty much a beginner, know the rules and play whenever it's one of the inflight games on American Airlines, but maybe once or twice a year. I don't know anything about openings or middle game or formations or anything like that. I hate to say something that will sound pompous but I'm the kind of person who knows what "standford-binet" and "weschler" are referring to, so I'm a part of "that world", whatever that means.

Anyway, I used schess_db, apparently a very good chess simulator. I selected magnus carlsen as my opponent, and actually had a pretty good game.  I played as black. Here's an imgur of screenshots. First image is my strongest position in the game, followed by my verge of collapse, followed by my defeat.

Here's the game:

Thanks!
