There is a mental schema that doesn’t quite explain this, but it’s basically where we think and vividly imagine that we will die at any second, whether by fatal illness, natural disaster, hit by a train, etc etc. It reminds me a bit of what OP described, holding something precious and delicate and imagining dropping it on the floor . I do the same when all the time , always expecting all screw up
