It's a real thing.
Many techniques have been used throughout history. The most modern techniques are covert. The technology available now makes those harassing/ attacking difficult to defend against. However, there are those who are truly suffering, but are actually suffering from causes other than organized gang stalking attacks. Some are delusions too. It must be very stressful to go through such suffering regardless of the cause.
To someone who thinks they are being attacked, stalked in some manner I would think it prudent to consider the following.
1. Keep records of all details of each encounter, other witnesses present, collect their contact info. Also record time, dates, pictures/ video of environment such as nearby vehicles and license numbers and tangible evidence. It should be written in a sturdy bound journal to have with you at all times. It can be transferred to an electronic backup. Another method is to record audio/ video notes and transcribe to a backup later the
same day. Those are simple basics of the start of an investigation. Without those details, years can go by with no resolution. Any outside help from law enforcement or private sector will require evidence which only you can collect.
2. The victim should step back and look at the situations objectively and ask themselves the following.
A. Could these be coincidental?
B. Could these be demonic manifestations? If so, why would they be interested in me? Have I been dabbling in the occult or associating with someone who is into a demonic practice/ religion? If not, am I a believer that has recently started attending church and growing really close to the Lord? These are common reasons for the enemies of God to try to connect or to attack.
C. Could these be delusions from a mental illness? If so, sometimes there are simple nutritional deficiencies that can be the main culprit of everything from irrational fears, anxiety and even delusions.
3. Most important is to make sure the Lord is your protection. The only way you can begin to know that for sure is to know for sure that you have a home in heaven. Here is where it starts.
