Good answer Astri.
Aloha callie,
Marie mentions to not have electronics within four feet from you at night. I've had Damon from
Intentional Environment out to my house who walked through and showed me the electrical and wi-fi noise levels we were getting in our bedrooms depending on which breakers/electrical lines are active in our home. One breaker made a 6000 unit swing in both the master bedroom and our son's room. You can then set up a remote breaker switch for the evening if the lines that have the biggest impact aren't also running something important. In that case, you'll have some more adjustments to make. They also will make Feng Shui suggestions, as well as Dowse the property. Needless to say, we had a good time talking about Feng Shui and Dowsing issues he's come across in various properties throughout the years. HE may be able to suggest someone out in your area if you are interested in pursuing it further.
Best, Shawn
