This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

Exp Dermatol. 2014 Jun;23(6):391-2. doi: 10.1111/exd.12386. Shedding new light on the role of the sunshine vitamin D for skin health: the lncRNA-skin cancer connection.Holick MF1.

Throughout evolution, vertebrates including humans have depended on the sunshine vitamin D for their calcified skeletons. As our hunter gatherer forefathers ventured from the equator, their skin tone became much lighter in order to permit an adequate amount of ultraviolet B radiation to enter the skin to produce the vitally important vitamin D.

Although sensible sun exposure does not significantly increase risk of skin cancer, it has remained a mystery as to why.

Jiang and Bikle in their viewpoint provide a novel insight as to how Mother Nature was able to balance the need for receiving adequate sun exposure to produce vitamin D while limiting damage caused by the DNA absorbing the ultraviolet B radiation. Long non-coding RNAs which are plentiful in cells have a dual personality. Some enhance malignancy, while others act as tumor suppressors.

Jiang and Bikle provide compelling evidence that these long non-coding RNAs in skin cells are responsive to 1,25-dihydroxyvitamin D3 by decreasing their carcinogenic activity while enhancing their tumor suppression function presumably as a strategy for reducing ultraviolet-induced non-melanoma skin cancer.

Mother Nature got it right.

Sensible sun exposure is important for maintaining an adequate vitamin D status. Once formed in the skin, vitamin D can exit into the circulation to carry out its physiologic functions on calcium and bone metabolism. Some vitamin D however remains in the skin and is activated to interact with its vitamin D receptor to control cell proliferation using a variety of strategies including interacting with long non-coding RNAs to reduce risk of photocarcinogenesis.

A description of the experience

Croll, Oswald - Preface of Signatures – 16

For God hath placed the greatest good in the most secret place, and the lesser obvious to sight. In the centre he hath created all virtues collected together, which in the superficies are dispersed and diffused: and which is wonderful, all celestial stars, which in heaven are manifest in their corporeity, in the earth also with their spirits lie occultly closed: and as the celestial Sol by its spiritual heat generates all things in a terrestrial manner; so the terrestrial Sol by its spiritual heat, creates, and regenerates all things spiritually. By the celestial Sun, the spirit of the Lord in Nature operates in all naturally; in the terrestrial sun the same spirit effects all things, but spiritually. For the spirit operates by no other medium then by the Sun, because in the Sun only, and not elsewhere, he hath corporally placed the tabernacle of his habitation. [Psal. 19: ver.6.]
