there is one thing i don't understand.. basically every time i try to nap, when i'm close to drifting away (i think) my whole body jolts itself awake.. not that old falling sensation, but kinda like when someone claps and yells "OI!!" and you get a shock.
I've experienced that a fair bit! Sometimes it means the end of my nap ... or sometimes I ignore it and catch a few more Z's. :)
