Hah! I found that joke to be interesting. Nice image too. Does the image have a source?
Here are a couple of tips on how to get the most out of your sleep though.
1 - Stay light - avoid eating before sleep and also visit the restroom.
(This allows your body to focus on recharging you, not digestion)
2 - Ensure a restful environment - dim lights and noises affect sleep depth.
Sweet dreams. ^_^
