Something weird happened last night (well, technically, last morning).
I was in bed and couldn't sleep, mulling over thoughts —that's a normal occurence for me, nothing weird at that point.
I was following some tangent about the spelling of vowels in French, and then, something about long vowels… but then there was some noise outside my room (this was in the early morning) and suddenly I not only completely lost my train of thought, but also temporarily lost the ability to form any coherent verbal thought… instead my thoughts were being replaced by visual white noise; I tried hard to find back what I was thinking about, but instead I was seeing what I can best describes as a lot of hatchings, like, densely packed sowilo runes… I was not asleep, and this wasn't a hallucination either, this was something I was visualising in my mind, in lieu of thoughts, while still fully awake and aware of my environment; but appart from a few isolated words that popped here and there, I was at that point rendered incapable of complex verbal thought, instead being reduced to raw feelings.
That was not really pleasant, it was rather scary and frustrating; though I think after a while I just fell asleep from mental exhaustion.
Someone suggested I accidentally entered a meditative state. Well if that's what mediation's like, I hope it doesn't happen again.
