It is Tetris' birthday today and I spent some time reading about the video game in the Wikipedia page. It appears that this popular video game is responsible for the Tetris effect. This effect is about dreaming Tetris shapes when drifting off to sleep, or seeing images of falling Tetris shapes at the edges of the players' visual fields or when they close their eyes. When I read that, I immediately compared the Tetris effect with the effect I have as a professional gambler, dreaming of playing cards and decks when I used to play blackjack in the casinos, dreaming of poker tables after long online poker sessions and seeing images of blue and purple squares after extensive trading in Betfair. I believe many online gamblers have witnessed some of those effects at some point in their lives. People can be easily obsessed with their work or hobby but I don't think it is actually a disadvantage. In all honesty, I believe it is a gift.

When I played blackjack at the local casino as a soon to be professional gambler for more than 10 hours each day, there wasn't a dream I had which didn't include playing cards. I also saw playing cards briefly when I happened to close my eyes. I don't have that particular Tetris effect nowadays since I only play online poker regarding card games, but that story reminded of my past experience. I'm sure a lot of you had it sometime in your life.

Being workaholic and putting a lot of energy in your work or hobby will certainly lead to the Tetris effect in my opinion. Besides, we all dream of things that reside in our daily thoughts or things we want them to happen. Work is one of them if we are really interested in it, if we are enthusiast about it. Professional gambling is one of my biggest love affections and that is why I experience all the above. However, I can't remember whether losing or winning the previous day influences the effect in any way. I guess we usually dream of winning money, what's the point of dreaming of losing days?
