The above two slides are from a talk by famous UFO investigator Jacques Vallee. The talk came up because scientist Garry Nolan (who sometimes works with Vallee) mentioned a later aspect of the case (a star-shaped mark on a photo and a giant UFO nobody noticed) in a recent interview with Tucker Carlson.
But someone in the comments pointed out the likely cause in April 2022:
And indeed, there is a strong resemblance:The Paisley Wave 4 months ago
With all respect for Dr. Vallee, the 'crosshair' marks may have a simple explanation. Search for images of blowdryers and you'll see many, especially the older ones, have metal crosshair-shaped grills at their openings. They get hot and can burn the skin leaving marks corresponding with their shape, a crosshair. Note that most of these appear on women, who are more likely to use blow dryers.
Vallee discussed this hypothesis in the video, but, for reasons that are not clear, he dismissed it.
As well as the dimensions matching, all of the various shapes are shaped of hairdryer grills:Of course, we know, we've tried to look at that and say, What kind of symbol is it? Well, the first thing we thought about is, if you look at our hairdryer, you know, you turn the hairdryer towards you. And you look at the end of the hairdryer, it looks like this. Okay, so we thought maybe, you know, this, this woman, I mean, women use hairdryer more than we guys do. So maybe she burned herself with their hairdryer. Well, if you try to do that, you're going to get burned, alright. But it's not going to look like this. Okay, you will have a burn. And so, so it's not that. Although in some cases, the dimensions are pretty much the same as the ones on the grid in the front of your hairdryer. But it's not always the same pattern. As you could see the pattern changes. Then you look at, you know, ancient literature and symbol books of symbols, and so on. And there is a pattern that looks exactly like that. Three, concentric circles, and radio lines. And that's a pattern of Atlantis.
The marks look very like superficial burns from a brief contact.
The partial marks could obviously come from a hairdryer at an angle (as seen in the medical journal image).
So his dismissal of hairdryers (and the subsequent leap into Atlantean symbology) makes no sense. Hairdryer is by far the most likely explanation.
UPDATE: The hairdryer owned by the individual in Vallee's case matches her burn:
Vallee's case is in the French Traces circulaires cutanées database as case 151. In the questionnaire, she says she has a hairdryer, a Lidl Silvercrest. She did not have a photo.
Posted publicly here:
I found a video of one.
You see the slightly domed grill which means you will get only partial contact, depending on angle and pressure. Note the heating elements are very close to the grill.
It matches her burn.
(slight perspective distortion as the original image is at a slight angle and skin is not flat)
Given this coincidence, and with the other evidence in this thread, I think this is very likely an accidental burn from a brief bump against the skin, forgotten, and then the burn noticed days later.
