The simple answer is yes, but only when a specific action happens.
I have had 2 cases where clients have contacted me several months after their homes were cleared of negative energy through my home healing, to say they had experienced an influx of negative energy. They could feel the change. It was a feeling of cold and discomfort in a now normally light and positive environment.
The first case was a home in California. The earth stresses were very high in this home, which was due to the site being on an excavated area of mountain that had been cleared to complete the housing estate. There had been some earth drilling in the neighbouring property, preparing for some new building and it was a couple of days after this drilling that the client experienced a very strange feeling in their home during the night. A weird energy passed through the house and was very unnerving. On investigation, I discovered one of the ley lines passing through their home had been damaged by the drilling, turning it negative, and this had caused the negative flow of energy to enter their home. I was able to repair this ley line back to its original purpose of bringing in positive energy and the client confirmed that all positive energy had been restored again.
The second case was a home in the UK which had benefitted mostly from psychic clearing, but had had negative energy blocks and broken ley lines. The council had replaced all the street lamps in their road, of which one was directly outside their home. On carrying out some DIY work inside their home one weekend which required taking down an internal wall, they were aware of a sudden feeling of cold and discomfort. It felt very eerie. On investigation I found that the street lamp had disturbed a ley line that travelled through their home and was letting in negative energy. Once restored they were pleased to report that the energy had returned to positive again.
So, it appears that ley lines can be damaged again after home healing has been conducted. If you have had your home cleared, be aware of any building activity around your property, but also any strange feelings within your home as these could be signs of a broken ley line.
