Creativity for me is best when it is twilight

Creativity is at its best for me in twilight (metaphorically speaking).
Very bright lights/loud sounds = Make me purely receptive and outer focused (all senses are basically receptive in nature, right)
Very low light/low sounds = Make me sleepy and comatose.
So when there is just the right amount of visual/sound intensity,
I can simultaneously access the inner and outer spaces,
And let the outer cues stimulate the inner space well.
The thresholds of sensitivity may however vary from person to person.

Creativity is an “inside -> out” action.
While, sensing is an “outside -> in” action.
There is ‘sensory appetite/hunger’.
When that is adequately satisfied,
Naturally, there is a sort of retreat to the dark to digest/process it all.
This processing is then what I think is often the source of creative works.

Information vs. Processing

When [Information] is less than [Processing] = We go outside, we socialize, we seek experiences (sympathetic activation – seek and explore)

When [Information] is greater than [Processing] = We retreat, we isolate, we hermit ourselves [parasympathetic activation – rest and digest]

This dynamic can also be clearly seen in:
1 – how we search/acquire physical food
2 – and then consume/digest/assimilate it
Just like physical food is for our physical body, [impressions food] is for our psychic body.
We first explore/seek and go on adventures to acquire experiences, then once we have acquired enough, we go low key and possibly isolate ourselves to digest everything.
In our world systems, we are expected to work perpetually with little breaks.
So we often feel guilty for profoundly retreating for too long.
But it could be that is what you need.
Follow what your deepest being is telling you.
