1. Must be warm. Usually this is not a problem at all but when Melbourne weather goes from uber hot -> uber cold sometimes I need to go get gloves/socks out. xD
2. Must not be too hot. This usually comes from when I close the door for some reason (eg lights on when going to sleep - normally I leave it open so cats can come in and out) and I wake up in the morning at like 5 and then thats it.
3. Must be sleeping on the side which makes me face the door/way to get out. I have discovered that it is not simply 'I sleep on my right side' because when I've been away on school camps etc I've noticed that I *never* face the wall unless I'm ridiculously tired in which case it doesnt seem to matter, but that doesnt happen too often.
I also somehow manage to turn new pillows into major flattened wrecks within a week. I much prefer new pillow high-ness but I've gotten used to icky flatness because I squish them all xD
