Peace during medical procedure and good test results

I’m going for a medical test and I have to have anesthesia and before I wake up at home every morning I have horrible horrible dreams and I’m afraid that I after going under the anesthesia that I’m going to have those dreams and I’m not going to come out of that right so I’m praying that the Lord will help my mind. Be a peace and have happy thoughts peaceful thoughts. I’m also praying that my results are fine. I’m so nervous about this. Thank you thank you Lord. In Jesus name I pray amen.
