Didn't Benjamin Franklin sleep at his desk with a stick propped under his elbow, so when the stick fell out he would invent stuff? I remember hearing that somewhere but now I can't find it

Maybe but IIRC Tesla would hold a ball in his hand before dozing and dropping.

Maybe Franklin did this with the key and it gave him the lightning rod idea
