Thanks firekeeper and everyone for your reply. I will ask my wife if she is interested in posting (not sure how open she is to this). To answer some of the questions.
1. She thinks its remote reiki or reiki transferable through objects which certain people give (gifts etc)..does this make sense?
2. Yes she has been to a doctor (goes regularly) and her sugar levels are normal with the help of medication. She also does reiki to maintain her levels and recently she has noticed a spike in her daily reading which leads her to believe what I mentioned above.
