Thank you for your lovely reply, @LeaningOnTheEverlastingArms. I've heard similar from many others.
I'm interested in this for reasons I'll try to explain a little bit. Friends have sometimes said I walk with one foot in the real world and the other in ... another world 🤔 but I do know what they mean! I have, unusually, been diagnosed as not having a personality disorder or any MH condition other than depression & low-grade CPTSD. So normal, yet the fact these other diagnoses were carried out says something.
I'm writing - so slowly, a crippled snail could write faster - a thing about the ways human thinking has changed over time. This is why I'm so interested in the 7th century BC (and, much later, the Enlightenment) and am re-reading ancient mythologies. People used to think with their instincts; intuition if you like. Obviously they were capable of analysis, but it meant something different to them. For the mathematicians of Babylon, the engineers of Egypt and Greek philosophers, knowledge 'came to them', after which they tested, explored and codified it. Leonardo da Vinci was like this, and I'm sure geniuses in every discipline experience it. But for people before around 500 BC, this was the only way knowledge was gained. It came directly from the gods.
People heard the voices of the gods. These days, we experience what they did at crucial moments; we use terms like 'inner voice' or, sometimes 'the third man' in major emergencies, when survivors report hearing a literal voice telling them what to do. You would doubtless call this the voice of god. I might call it your amygdala! In the early to middle iron age, it was an everyday occurrence.
To an atheist I must be deluded, deranged, mad or something.
This is where you're likely to get cross with me. Deluded and deranged are loaded words. I propose that short-term psychosis is far more usual than anyone admits, and that is why the DSM's two diagnoses (schizophreniform disorder and brief psychotic disorder) are said to be rare. When it happened to me at 19, I was working for a psychiatrist so I took it to him. He told me it's really normal in the late teens, early twenties, particularly for women, and not to worry unless it went on for more than a month: it didn't.
His hypothesis was that the massive hormonal disruptions of puberty, and the subsequent reconfiguration of the brain, could reasonably be expected to produce a few short circuits. Now we're learning more about both hormones and neurology, it looks like he was on the money. When we add in the now-recognised phenomena of PMD, PPD and pregnancy psychosis, sharp changes in oestrogen levels look likely culprits.
I hope I've managed to show we may not be different, except in the way we interpret things. I'm not saying your interpretation is wrong, just different from mine. One last similar-but different experience: miracles. I'm a massive fan and follower of Derren Brown. I guess you can see why!
