Image in you mind? That's 2 dimensional as well. Too literal.
No, I meant 1 word = 1 definition (2 dimensions). Rather than conceptual understanding. I made up the word hiwoo, but it still has meaning based on context (the third dimension in this case). The actual, literal meaning of dimensionality will stop someone from understanding that.
You were born in 91? Wow, guess you don' remember all the 90's Star Treks. What about Star Wars or LOTR or Beavis and Butthead? All that pop culture stuff. You haven't experienced any of it? There is some good stuff now, but I haven't seen anything on the epic level in a while (ok maybe Beavis and Butthead isn't epic).
