You know you spend too much time with your head in an imaginary world when you walk into a pub and absentmindedly order a bottle of kanar. I was'nt even drunk when I said that, just elsewhere in my head... I've also managed to ask for a raktajino in a cafe once, and took two entire seconds to readjust my consciousness when the girl just blinked at me.
Any examples of reality confusion from anyone else...?
