I think if summat like that genuinely happens to you, you spend a lot of time afterwards trying to convince yourself and others - I'm not sure I'm convinced that anyone that happened to, even if they didn't think it was massive, would just chuck the one bit of evidence..
Yes, that may be the case. Husband and I both saw the thing we can only rationalise as time slip and have both had multiple paranormal experiences - so we'd fit into the category of witnesses to this (although all we saw was a stupid cat, not an entire 1950s' shop or something which would be ace...) But for me, the psychology of it is, indeed, that I feel like I want hard proof and if the cat had handed me a Thermos flask, I'd have shown it to everyone I ever met, sent it for forensic analysis and then had it placed in a display case in a museum forever and ever... :Hobbes:
Oddly, I also feel the need to convince myself, let alone others. Even as it was happening, we were going "WTF?" and it felt, on one level, kind of .... exciting. Like, we just both saw that - you saw what I saw. We've both been on this planet for 5 decades and neither of us had ever seen a see-through cat (in husband's case, with different flora behind it). So I know what I saw and I know I really saw it and better still, I know someone else saw it and that is what we saw that night, and I made him recount to me exactly what he thought he'd seen before I said a word about what I'd seen - so all that weight of experience to convince us that no, we weren't dreaming, it's not tiredness, it's not one of us has gone nuts... But yes. I wish the thing had handed me a Thermos! There is always a part of you that still questions it.
Yes, the podcast made that point that people who see this 'bad editing' or 'jump cuts' in time - whatever causes it - often go on to have other experiences or have had previous. I found that really intriguing as well.
