Good news you are not really mad after all.
Those of you living to play games on your Aquila Computers PC (hopefully you have one, if not why not?), will be familiar that after you have reluctantly packed up, and left your game to go to bed, as you begin to unwind and try to sleep. It begins! You can hear the game music, sound, and it comes back flooding into your mind. Don't be alarmed! You have not developed some kind of mental illness, and no it is not a psychotic episode you are experiencing.
