[The Matrix] How different was The Matrix from the real world?

So, there seems to be an implication that the Matrix program was designed to be similar to the real world, there seems to be some implication that a decent bit of their replication of 1998 was changed to better suit their purposes.

The Zion might be seen as suggesting that the Real World had a lot better technology at that point in time. Additionally, The Oracle said *"Every time you've heard someone say they saw a ghost, or an angel. Every story you've ever heard about vampires, werewolves, or aliens, is the system assimilating some program that's doing something they're not supposed to be doing.", which could mean

A) The Real World didn't have stories of vampires, ghosts, etc.; these were all invented by programs in the Matrix

B) The real world did have these stories, but they never made it into The Matrix

C) The Matrix either took inspiration from Ghost stories or independently made similar programs entirely by coincidence

I personally find the last option to be the least likely, imitation seems uncharacteristic and it seems unlikely that the Matrix would independently create the same creature.

We also get a few other suggestions, like when Mouse Asked if anyone could know whether the sensations in the Matrix were like real life or simply guessed at by the machines.

The Architect used things from the human pyche when he made ghosts and vampires and such. It was part of the effort to force the mind to accept the simlulation to include uncomfortable but familiar things.
