1) The Chinese Poet
the kind where the head turns a complete circle, or sometimes swings a little like a pendulum, just like how a Chinese poet shakes his head when he recites a good Chinese poem!

2) The Elevator Needle
you know, those old-fashion elevators where the location of the elevator cabin is indicated by a needle? These sleepers' head will slide slowly, either left or right...and then goes right back to starting position [straight up]. And the process goes on and on and on...until we wake them up!

3) The Venus Fly Trap
he he....in typical fashion, this type of sleeper sleeps with their mouth hanging open - once or twice, you may even see the drool...yeap, just like a Venus Fly Trap!

4) The Fisherman
oh, this is rather common, where the head bops up and down. Just like the fishing rod when you go fishing. Especially when using the Apollo. You gotta jerk it up and down to get fish!

5) The Yoga-Neck
ouch..this is rather painful to watch. The head starts of like the elevator needle, only difference is that it'll stop when the head reaches the shoulder. And it stays there! So you can really see the stretched muscle [read : feel the coming pain] on the neck. Ouch!

6) The Troubled Sleeper
this type of sleeper gives me the impression that they have the world on their shoulders. They frown when they sleep! Their forehead is wrinkled, and their eyebrows almost meet in the middle... a little disturbing to watch, actually

So which one are you??
