The night is dark and full of spirits, and they want to help cure you of your fear of death. Because when your work here is finally done, you'll be able to join them in their nightly dance and jail-break out of the prison of matter. 

 

I mean, if you so choose.

Get out there and open yourself up to the world of the spirits.There are all kinds for you to meet: animal spirits, nature spirits, ancestor spirits, star spirits, you name it. The good ones don't want anything from you, because you don't have anything they need. 

 

You really have nothing to offer them but your company. Be generous with it, and they will soothe your stresses and anxieties and peel away your terror of the grave. Guaranteed.

"When the night's skies held more than stars."  Why the past tense?  From UFO Newsclipping Service, 1979.

"Deep was the forest and thick the blackness around them, and many feared they would be lost, never to be seen again.  But with proddings, pleasings, coaxings, and soothing words, all burst from the darkness.  They stood upon the mountain top with all the world spread before them under a clear, golden sky.  How quiet they stood, looking and looking at the huge expanse and whispering thanksgiving that the forest was behind them."
