"at what time of the day are we thought to be most creative?"-This is
the way the question is phrased in a quiz.  I've looked at sites
referring to'4.48am Psychosis' which is a play by Sarah Kane. She used
the time in the title referring to the time at which many people
commit suicide and there are other vague references to 'lucidity'
being at the optimum at this time. The more factual sites, however,
acknowledge that it varies from individual to individual e.g. Time
magazine's archives.  I want to know if there is a generally accepted
period in the day when people are more creative.

When you are asleep you are the most creative. Last night I dreamed
about a cat who trained horses to do kung fu, and I dreamed about a
cat who saved the world from the evil dictator Dogler. If that's not
creativity then my name is Ludwhig Von Bheetoven,

Well, one would have to unambiguously define "creative" in order to
begin answering what time of day it's strongest.

I think what time we are most creative depends on who you are. I am a
guitarist and I find I'm most inspired around 2 am .. that's when I
find the notes flow from me. This is usually because I'm overly tired
and haven't the time or energy to process a real thought. It just
happens and it's creative :)

This is to make a point that if you DO find a statement, then if it
does not include my hours then it is wrong.

I have two modes. The first one is when I do not have to wake up early
(and even if I do have to). During this time I start to work at 1 am.
The silence and the absence of light are perhaps the biggest help.

When people around me do break my late schedule, I can start to work
at 1 pm. During those times I go to bed very early, about 11 pm - 1
am, and usually feel sleepy before I go to bed.

When I work at night, I never feel sleepy during the day, or when I
manage to fall asleep (6 am - 1 pm, especially if I can stay home). I
fall asleep when I stop the work.

when your are reaching a state of sub-conciousness, so you are not
likely to be distracted by your senses and then you can focus on your
intuition.

I believe that most people have a hormonal cycle that "resets" itself
usually midday like noon-3 for most people and again at the same time
at night. If you are awake when one of these two periods passes you
will more likely stay awake for a while longer and vise versa. Perhaps
this effects when you are most creative?
