I can help you out with any of the above cases and many more, by providing an effective cleansing with Reiki (I have 2nd level Mikao Usui, certified by Master Carla Marcelino), neutralising any negative energies. It can perfectly be done at distance and only takes a few moments. I only need some photographs of the place (ideally of the interior). I don't want to know the location.
Energetic cleaning of home or work place
No, as these are physical causes of negative energy. This method only works for spiritual energy.
