There is an intersection in our area that is always a traffic jam. Interestingly Henry, our little giggercounter goes off when we are in the vicinity of this intersection crying in discomfort.
The phenomenon is called a ‘demonic road wave’.
This was made by an archon hybrid demon.
Essentially, if you are in one of these you are being bathed in demonic energy, which lowers your frequency. You can counter this with Reverse half moon while in the stopped traffic.
