Who's trying to fool anyone? Not me thats for sure. in order to be trying to fool someone i must first be suggesting what they are. I posted this thread to find out that very thing.
I have let folk tell me what they think they are and i have then looked into all the answers. I still don't know what they are, therefore it would be hard to fool anyone with anything.
I know it is not dust on a lens, as they were visible and reacted to light. Thats the only thing i am certain of tbh.
They were there, i don't know what they were, but i am keen to find out. I'm looking into Mary's suggestion of ball lightning more closely, as some of what i have read sounds similar, but then some of it is nothing like these either. So i don't know what to think.
I have an open mind, but I'm also not easily fooled.
