The phenomena is called 'normalcy bias'.

It's how 'habits' are formed. What's weird is that it usually happens only in one direction.

When I was learning SCUBA diving at Fort Lewis, the instructor told us we would discover this phenomenon after we had done nothing but night dives for several weeks.

You would become so accustomed to it that going back to dive during daylight, everything would feel really 'strange' and to expect it

Same when handling small brass for so long. The mind considers that 'normal' and then, like you noticed, freaks out dealing with big stuff.
