To see or dream that you are at an arcade implies that you are living your life too seriously. You should pause to reflect on a time where you were truly happy and full of pleasure. It may also mean that you feel as if you have been used by someone, or perhaps you have taken advantage of someone else. You may be trying to avoid unpleasantness and deny that you are experiencing problems.
The arcade is a diversion from the hardships of life.
If you dream of walking or playing games in an arcade, attractive temptations will soon be put before you.
If you were just walking past an arcade or looking into it, you should avoid repeating any secrets you hear, or else your own will be betrayed.
