Mh well.... some times if I have holidays and play about 14h a day (most onlinetime 300h/month in holidays) I sometimes dream about WoW.
But this is normal if you do a thing that intensive.
And yes, I have a girlfriend and some friends too. I'm able to play that much because of my girl studies and have to learn for school. So I have much time
The thing with "dreaming about" was rather ment as "I wish all the time". I'm not that good in english... in germany we say "I dream about" if I really really want to get something. That dosn't mean that I dream about it at night
