Welcome to HCM
We understan your concerns
Video games or computer gmes are a peril. Numerous studies have shown the ill effects of gaming. I am very glad that you got an experience of it and am fairly sure that you will never repeat it. Now for the symptoms you mentioned. These symptoms arised on your body due to disorientation
of body with the real feelings. When you are in the the game, you were behaving like one of the character and slowly you lost your touch with the real world. When you returned your body and mind became disoriented with the present. Like we struggle on entering a dark room from light, and after some seconds we will be able to see things.
But don't play computer games for more than 1 hout, keep time tble and stick to it.
