May be a circadian rythm thing? ...I have heard of neurological events as well but all I could find on the web was about sleep...Anyone else here know about that?

Here is what we learn in ChiGong...

03:00-05:00 Yin Lungs
05:00-07:00 Mao Large Intestine
07:00-09:00 Chen Stomach
09:00-11:00 Si Spleen
11:00-13:00 Wu Heart
13:00-15:00 Wei Small Intestine
15:00-17:00 Shen Bladder
17:00-19:00 You Kidneys
19:00-21:00 Xu Pericardium
21:00-23:00 Hai TripleWarmer
23:00-01:00 Zi Gallbladder
01:00-03:00 Chou Liver

That might be a good time for you to meditate.

Just a thought...
