I never knew Edison did that. And truth be told, I’m not sure I could perfectly conduct this experiment myself. I’m not the most pleasant to be around when my naps get interrupted haha
But I will say I have experienced this before and didn’t know it had a name.
More than one occasion, just as I’m the most tired and ready to fall asleep, I’ll notice a brilliant stream of ideas. Several times I forced myself back awake and grabbed my phone to type down some what was going on in my mind. Some useful stuff has definitely come from that.
Thanks for sharing this.
