In addition, here is my experience...
Although it has just been 3 days after I have cast this spell for someone to think of me --- something I have casted on the same person 3 years ago and have recasted just recently.
I felt there was something wrong immediately after I have casted that spell as it seemed to have backfired on me as I have been the one thinking about the person constantly. However, I have casted this realization spell early on today --- and for some reason I don't understand, it felt like everything is going to be okay. I don't understand it as although it hurts what this person has done to me --- I also at times felt at peace that everything was going to be fine. Does that make sense?
