I have used Tarot cards to give me some perspective on some descisions. As a side effect I start to experience a lot more of unexplainable synchronicities in my daily life and in connection with the decision. Most striking example: I was at a point where I needed to decide if I should break up with my girlfriend. I was doing the taro spread to get the answer and at the same time my girlfriend called and told me that she met this one guy and she would like to go on a date with him.
