Submechanophobia!
https://en.wikipedia.org/wiki/Submechanophobia
As a kid visiting museums (with varying degrees of interest), I began to notice that I had an increasingly uncomfortable reaction to model sailing ships. Sailing ships only, mind. HMS Hood = no problem.
This grew over the years to the point where I now get a physical reaction. The Airfix classic ship size I can cope with, but as the models get larger I suffer anything from shortness of breath to feeling sick. It’s not only models: things underwater and boat hulls in general (especially water lapping against them) can set me off.
This has led to some rather embarrassing situations as I have worked in a number of navy buildings that often contain a model or two. In one location I was somewhat taken aback to find they had plonked a huge model of Victory next to the Gents. Caught short one day, I had to close my eyes and be led by hand to blessed relief by a bootneck, who I think is still laughing now. Of course, this was after I got married which may well have been different had the Mem not been similarly amused: our third date was a visit to the Mary Rose…
I’ve not met anybody with a similar problem, apart from the occasional agreement that stuff underwater can be a bit creepy, so it’s nice to know it’s not that unusual and there is a name for it.
And you never know - I might even be able to claim a PIP on day and get some of my tax money back. Every cloud, an’ all that.
