Cleared the re-exam after imagining telling my mom

The story

This was before I read Neville. A couple of years ago I had 3 exams out of which I failed one (subject C), and I was supposed to take that exam again 2 months later, but during that time I didn't study a single word and was worried that I might fail again. So, a day before the actual re-exam, I sat down and imagined what happened when I actually passed the other two exams of the subject, say A and B. I remember being really happy and going to my mom and telling her that passed the exams. I thought I should do the same thing this moment in my head, and instead of those exams (Sub A and B), let's just change the exam in my head that I cleared, Sub C. So, I played this in my head, and went up to my mom and to tell her that I cleared the subject C exam and I'm really happy—the same scene that I actually did in 3D, just that I changed the result. And I looped the scene 2-3 times only because I was enjoying it so much, and then I woke up from that imagination session. After that, I didn't feel like studying, so I started watching a movie. The next day, I didn't appear for the exam. To be really honest with you guys, I wasn't worried; I wasn't calm...like numb.. whatever kind of feeling. A week later, results got updated, and guess what? cleared that re-exam.
