About a healing experience I had in the past ...
In Romania, about 19 years ago or ao, someone told my parents about a bio-energy healer. I went for the sessions of healing with the healer to revive my hearing.
The sessions were done daily in the evenings for maximum 2 hours. On the 7th day, I arrived home from the visit for the daily session, I experienced a brief moment (1 to 5 seconds) when I was able to hear perfectly my own voice and the voice of my parents. I even understood what my parents were talking about (they were behind my back at that time).
However the sessions were taxing me too much that I developed a side effect, constant headache due to the perception of the background static noise similar to what you see on the tv when there's no signal (the old tv that shows static).
I had to stop doing the sessions cause the headache was interfering with the school and the studies. Sadly the healer left Romania back to his country.
That's my experience.
