If you have doubts about the origins of your unreality, I seriously recommend an EEG. If it is negative, you have learned a lot. My trauma at age 17 also occurred simultaneously with my 1st cannabis intoxication.
The cannabis may have triggered the seizures I experienced. The cannabis may have mitigated the seizures so I did not lose consciousness. One thing is certain....the cannabis confused the incident and
contributed to the inability of health professionals to render an appropriate diagnosis for 40 years. I was mentally ill and living in fear and ignorance from age 17 to age 57, when I discovered information
that explained everything in minute detail. I smoked the cannabis. I experienced an epigastric aura, which is a lesser seizure that announces a larger temporal lobe seizure is pending. I experienced
the temporal lobe seizure with epileptic discharges every 4 or 5 seconds for about 3 minutes. Each discharge was accompanied by dolly zoom hallucination. When they were done, so was I. I lost my emotions.
I lost my libido. I went sleepless for 2 weeks. I developed agoraphobia. I was a worst case scenario, according to the neurological texts, as my "post-ictal psychosis segued into an affective disorder of major depression". 40 years of focal temporal lobe seizures,
5 major depressive episodes, frequent ocular migraines, palatal myoclonus, depersonalization and derealization, etc. etc. If I ever do write a book, it will be titled "Bigger Fish to Fry".
That is what a neurologist told me when he diagnosed my ocular migraines. He never thought to give me an EEG. The US wasn't that interested in the subject of migraine. The British were doing more research in that area. I solved my riddle by reading British neurological texts.
Now, epilepsy clinics routinely treat migraines, as the title of a recent British research paper explains "Migraine, the Borderlands of Epilepsy".
