I read your testimony. I note that you were extremely ill and afterwards experienced a great number of new sensations. A severe illness can cause changes in the brain due to swelling or other damage. That fact along with your statements about tingling sensations make me wonder if the illness caused some initial damage which was followed by several transient ischemic attacks (TIAs).
Symptoms vary widely from person to person, depending on the area of the brain involved. The most frequent symptoms include temporary loss of vision (typically amaurosis fugax); difficulty speaking (aphasia); weakness on one side of the body (hemiparesis); and numbness or tingling (paresthesia), usually on one side of the body. Impairment of consciousness is very uncommon. There have been cases of temporary and partial paralysis affecting the face and tongue of the afflicted. The symptoms of a TIA are short-lived and usually last a few seconds to a few minutes and most symptoms disappear within 60 minutes. Some individuals may have a lingering feeling that something odd happened to the body. Dizziness, lack of coordination or poor balance are also symptoms related to TIA. Symptoms vary in severity.
Other than the tingling
, do you recall experiencing any of the other symptoms? Have you consulted with a doctor about those symptoms? Have you consulted with a doctor about the other significant changes to your mind and senses?
Regarding the disappearing red light. You clearly state the red light was small and in your left peripheral vision. Human peripheral vision is largely devoted to sensing motion. Also, objects not in our main focus can disappear from our vision. These facts along with your description point to a quite ordinary situation of the meditation focus causing the light to not register until a slight shift in your body/head causes a shift in the light - implying movement. Since we evolved to react to peripheral movement, your focus was brought back to the light and it reappeared. Once you are comfortable with ignoring the light again and drop back into meditation, the light disappears again until you move and it reappears. And it repeats. Nothing mystical about it, sorry.
I understand the desire for there to be magic in the world. But there is a very real possibility you have suffered minor
brain damage which has caused these changes. The worry is that if you don't see a doctor, you could suffer worse - sooner rather than later. If this was Jesus/God reaching out to you then a visit to the doctor - where you describe all your symptoms to him - will only show a healthy brain and body. If the sensation were caused by damage then a visit to the doctor could save your life.
