Accidently created unwanted pattern

I've just done free flow 12. In the progress, I just laid still, let myself expanded. Instead of visualizing, I used affirmations combine with adding the feeling of my wish comes true. About the last 10 minutes, suddenly my body felt hotter, and unwanted scene just appeared and looped over and over in my head. I tried to keep myself calm and lead me back to the serenity feeling. But thing didn't work well. The feeling of discomfort became stronger, while the scene kept playing. I decided to quit before the tape ended by counting down to 10 and then 1.

I don't know if I manifest that thing and it will come to me someday or not. What should I do?

P/s: Sorry for my bad English.
