The Monroe Institute is a facility that’s researched various frequencies and studied altered states of consciousness, remote viewing, out of body experiences etc and the CIA enlisted their help to train their agents to utilise these abilities as spy tactics.
In one of the declassified documents from 1977 released by the CIA, it's mentioned that you can use the code 55515 to reduce pain from the physical body.
What You Do:
Focus your awareness on where your physical pain is coming from and repeat the numbers 5-5-5-1-5 until the pain is gone.
Anecdotal reports state an almost immediate reduce in pain after using this method.'
Placebo effect? Or Re-coding your body?
I did a bit more digging at it looks like there’s a gene discovered in 2000 (over 20 years later) that relates to pain perception also identified as 55515 
A NCBI page on this specific gene writes "These channels have been implicated in synaptic transmission, pain perception as well as mechanoperception."
(Mechanoreception is the ability to respond to certain kinds of stimuli). This gene is expressed predominantly in the pituitary gland.
Interesting right?!

Our Nature is so Godly. We only use such a small, small portion of our brain that we only barely scratch the surface of our potential. I’d love to learn more.
The question is, does this just shut off the pain signals or does it heal the cause of the pain? If it only shuts the pain off this could be dangerous lol

this is crazy. this “55515” stuff actually works, so does the rest of the document. this is crazy. why do you think they’d keep it a secret though?
I had a bad headache so I did this and it really does help Thank You for this.
