Back in 1.0 I would have a lot of XIV related dreams. The worst one was being lost in the Black Shroud. You can imagine how well that one went. The most recurring dream was of just being in Ul'dah seeing other players just walking around.
Might I add something silly that once happened to me: One morning as I was going to drive to my Uni, I had barely slept because of a long night of playing and getting to the Moogle fight, I press the radio button, and for a brief second I thought a map of the Shroud was gonna open up. With low opacity and all.
*grumble grumble freakin' shroud*
