I wasn't sure where to post this, chemtrails or here. It is superficially about 'sylphs'. However, they need such weak refutation, I decided the pages have far more to say about pareidolia within the conspiracy mindset, and the willingness to believe in patterns - if necessary, self-constructed - where non exist.
This page perfectly illustrates pareidolia, in this case in the sky. The author has taken a large image, and scoured it at all sizes and rotations, delivering crops showing in his honest opinion faces, presumably of 'sylphs' or some such. As a meteorologist, I have a life-long love-affair with 'cloud gazing', and as a graphic designer, inventor, artist and playwright, I would hope I have an active imagination. However, despite these possible qualifications, I can see nothing - not even the faces I am socially programmed to see - in these images.
