I find it strange that adults don't daydream.
I was one of those kids who live in his own head and was forever daydreaming and I as I grew up I never stopped helped I think by my early adult life been working on production lines/factories usually alone or so noisy ear protection was required removing any irrelevant conversation - I'd turn up, go onto autopilot and disappear into my head.
I still do it now, if I'm walking along the riverbank near where I live the world recedes and I visualise how it must have looked hundreds or thousands years ago and imagine the people/animals around then and so on.
It's both an escape hatch and a pressure valve for me - I also don't dream (or more correctly I do dream but maybe once ever couple of years I actually remember one) which I think is likely somehow connected.
My partner finds it odd because she'll come into a room and I'll just be sat still staring into space completely unaware she's entered the room.
This was a great article though, the idea of deliberately cultivating that state by sitting in an isolated place is attractive.
There are days where I hate the modern world (while accepting all it's advantages) - the constant distractions, clamour for attention from everything, the splitting of time into tiny increments in which everything must be done, it often feels like the world is just slightly off axis and I don't fit.
I've never found it an issue and an hour just sat in that state leaves me feeling refreshed and alert, the days where I feel the most flattened are the ones that are so busy that I don't get chance to do it.
