THIS or
another older one pretty much sum up the idiosyncracy of fears/anxiety but being on controls or aircraft is completely 'against the sense' of having such fears in ground or man-made structures.
Those talk of heights, but I think your case and so many of us, PPL or pro pilots regardless
I feel the same. Make me stand close to edge of high balcony, rooftop, bridge etc and I feel queasy. Flying with paraglider, glider or helicopter hundreds or over thousand metres up in the air, no probs.
As you yourself state, it's 'funny' mind trick.
I also noticed on myself that I recently became more sensitive to lateral movement during landing, while SLF in B737. Whether it's because I've flown more often recently and seeing the tragic aviation mishaps recent months, or just the fact that I've done lots of gliding training recently, leading to solo, makes me more aware of any movements. I'm not one of those who passengers who gasp and scream when experiencing low Gs on bumpy, thermal day in airliner.
Read those threads and maybe you'd find more yourself.
You don't have to read posts on 'private forum' to find folks experiencing this sort of feelings. Even professional pilots have their irrational feelings. Some heli pilots flying low-level or up to maybe 1000-1500' AGL feeling uncomfortable high up (where it's technically safer in case of engine failure, etc)
