Some claim that it's a myth.
And I read an explanation of why some might feel weird around new and full moon.
The moon affects tides,yes?In occult sciences,moon is associated with water element as well.
Moon has effect on water component.And human body is composed of water(around 60%).So,it is likely that moon has an effect on the human body and influence the mind especially during new and full moon when it is in straight line with earth and sun.
The explanation seems like a stretch but it might make sense to some. https://provinceapothecary.com/blog...you-what-you-can-do-about-it-by-shelly-burton
My grandpa once said that the moon phases rule our lives. I was about to interrupt him when I realized that the months of the year are based on moon phases, and when the month is over we have to pay our debts.
the next new moon is july 2, so I'll have some things to pay... Oh, well, what can you do?
