Liked it indeed, though I was kinda hoping it would be one
of those red devils mentioned in a link in another thread.
One slightly similar thing happened to me when I watched
for ages in horror at what appeared to be a rat-infested
black refuse bag in the alley behind my house. I could see
their tails and pointed faces as they scavenged away. The
behaiviour was so rodenty that I resolved to call the council.
It was only with the coming of the grey light of dawn that it
became clear I had been seeing just the tattered top edge of
the bag that had been ripped off a roll. As it rippled in the
breeze, it made the animal movements and its triangular
patterns had made noses and ears.
Walking at night I have also often interpreted some formation
of trees and fence or other roadside structures as a person
standing. The odd thing is the detail you can project onto such
an "honorary person": old, young, male, female, threatening
unthreatening. It's like the blobs of paint that make up a tiny figure
in a painting - when you get up close, you realise there are no
features at all!
I read recently that only something like 10% of what we experience
comes from sense data and the rest is supplied from memory and
imagination. Even so, some sense data is weird enough to keep
us in business on here for some time. This week I have seen a
lake monster and a bizarre morphing UFO. Only movies but baffling,
thank God!
