I want to make a remark about head implants and clicking noices.
Many people have implants; they come from a mix of abductions, rituals, abuse, manipulated food, vaccinations, radio transmissions, ELF, cell-phone, medicine etc.
Implants can be built in the brain made by the material input and software activations coming from satelite, cell-phone, medicine, triggering etc.
These implants can be activated when the mind is doing something like changing thoughts rapidly, thinking about new themes, or walking in heavy industrial electronic environment, travelling across tunnels, etc. These activations sound like "clicks"
This is a sign the implant is to reconfigure it's programming and/or reprogramming the mind in another compartment.
