I have a good friend who saw a lunar eclipse in 1976. It was between 8-10pm (most likely) in Tennessee and it wasn't a total eclipse, but he has always been troubled by what he saw. He was with a group of other teenagers and all they saw was a cloud traveling in front of the eclipse, while he saw what he describes as 'demons' dancing around in front of it. I said I would try and find out what I could, I also thought I remembered hearing or reading something similar years ago, but I can't recall any details. Everything I'm finding on Google isn't what I'm looking for.
Any help or direction would be appreciated. To this day that 'vision' bothers him. Thank you.

Your friend got scared by clouds infront of the moon? wow

Oh nice work man, that was really helpful ... just a fantastic input in general, so i'm guessing that means u don't have any relevant information then?

For the record, i don't really have any useful input either, however plenty of ancient cultures linked the eclipse to gods and demons. So maybe ur friends saw...dancing demons? Or he might have been particularly high at the time?

you offered about as much input as i did, but atleast u got to blast me well done!

In all seriousness, your friend should see a psychiatrist if its that bad to help him deal with the issues.

Very likely, all that was seen was the passage of some wispy altostratus or cirrostratus clouds, which, combined with the hour of night, and the somewhat reddish color of the moon, and the fact that clouds of varying thickness passing in front of the moon create pulsing, moving variations, created a visual which was interpreted as demons by this young person. It's called pareidolia, which is a rather common human psychological capability (think of the man in the Moon, hidden messages being heard on records played in reverse, seeing faces in the clouds, etc...).

What's not common is to be disturbed about such things for three decades.

It was likely a very common phenomenon of the human psyche...nothing to be disturbed about.
