I didn't notice anything like mentioned above, I just had sth like 2-3 WoW-related dreams, some fcking Icecrown and Barrens images plus one wow figure to whom I addressed with my RL friend's name. There was also I short period when I was playing sth like 5-6 hours every day and once during the conversation classes we were supposed to tell our friend "what we did interesting the previous day". So I said: "Oh, we went to Stormwind City to farm some lowbies in front..." coz it was first thing that came to my mind. Fortunately the girl I was in pair with was an ex-addict so she said "take a deep breathe and tell me about your RL"
