This is pretty interesting. I mean I’ve seen dogs dream vividly and am not quite sure how much I believe all them Babe the Pig-alike movies. :)
But I think the definition of a thought is a problem here. Everything we say (or contemplate of saying or trying to remember) is also a thought which precedes our verbal output. Those thoughts will inevitably be in a language of our preference. And actually in process of learning a new language that is often times the pivotal point - once your thoughts switch to a new language, you know you adapted it.
Interesting. As women tend to combat vaginal dryness later in life, guidelines like these are especially needed there. Pretty sure you very easily fall into a vicious circle of lubing, ruining cells which produce any remaining lube -> lubing even more. I guess the bottom line is to buy water-based lubes with some sort of an organic “gel” source and avoid propylene glycol/tons of glycerine/detergets (though those are harder to detect by name).
