Quandary

[Edwardo Piet]

You mean your own experiences of other things that you almost certainly incorrectly mistook for experiences of spirits/ghosts.

It's possible I suppose.  I wouldn't say "almost certainly," but yes, I suppose I can't rule out some sort of unknown science that no one has ever documented or heard of.

That's not what I was saying though. I am suggesting that you were looking at something commonplace and mistaking it for something more or you were experiencing illusions, hallucinations, distortions of perception or delusions.
