The mind isn't limited to the body

Scientists say your “mind” isn’t confined to your brain, or even your body from Quartz feels more like a hidden advertisement for a professor's new book than anything with solid research, but it presents the idea that the mind goes beyond the brain.

Meditation can change the brains of ordinary people and improve their health

Slow-moving brainwaves (around theta) may be carrying information around the brain, according to The Journal of Neuroscience.  It may provide more insight into memory formation and epilepsy.

Meditation Affects Cancer Survivors

Researchers find that meditation maintains the length of telomeres in cancer survivors whereas they shorten in non-meditators.

Lucid Dreams Produce Gamma Brainwaves

The Neurological Laboratory in Frankfurt discovered that lucid dreamers produce gamma brainwaves that operate at at 40Hz.

I've had a few lucid dreams which occurred before ever doing gamma brainwave entrainment. I don't think I have noticed any more of them since I've started doing gamma brainwave entrainment. What has everyone else's experience been?

A Data Analysis of Dreams

FiveThirtyEight discusses results of a dream analysis study from 1950 and a new study from 2013. Apparently, the majority of dreams were "bad dreams" in both the 1950 and 2013 studies.

I do not find that to be my experience with dreams. I would say the majority of them are weird - not particularly good or bad. It's rare for me to have a good or bad dream and even more rare to have a great dream or a nightmare. It would be interesting to see the dream distribution of people that have more good dreams than bad or neutral dreams to see if there is anything in common amongst those people.
