I have submechanophobia too! The thought of machinery/mechanicals/vehicles under water... Ugh!
Big black square grates at the bottom of swimming pools... Yes, you, 1970s swimming lessons! I was petrified of them!
Shipwrecks of huge ships and oversized cruise ships.
Very deep dark water.
Sink holes/holes in water, like the Blue Hole.. Aaagggghhh!
We were once out on the motorbike, Liverpool way, I believe. We rounded a corner and there was a submarine out of the water, up on stands... I yelled all the way past!!! Just no!
The edges of pound coins or those bloody awful ring binders with the vinyl type of really fine ribbed covering... Eeek! Add to that flock wallpaper, the bits in between the velvet part!
Hovercrafts! Anything large and inflatable, blimps etc. Yet I don't mind hot air balloons, probably because the inflatable part isn't enclosed?!
Cauliflower ears on rugby players, toenails (my own!) and anything to do with eyeballs!
Thick woodland next to unlit country roads.
Heights, especially the tops of cliffs/hills. If I see someone standing on one on the TV it makes me panic and it's not me!!! I can't go two rungs up a ladder or stand on a chair!!! And you can forget the bloody loft!!! 🤣
Dry microfibre cloths! Although I use them as dishcloths ok, when I get a new one out, it gets thrown across to the sink via my barest fingertips and drowned before I can pick it up properly!!!
Reading this back I have issues!!! 🤣🤣🤣
