Whether you're an adorable animal at a zoo or a hardworking college student, you need your sleep. Somehow you never quite seem to get enough, but every minute of sleep is usually appreciated and you usually don't appreciate the moment when your alarm goes off or when someone wakes you up. Being a huge animal lover, I love taking trips to zoos to look at the animals and see what they're up to. Somehow though, a lot of animals always seem to be sleeping when I get to their exhibit. So, the other day it occurred to me that animals in zoos very accurately represent college students when it comes to sleeping (and the various ways to wake up).

1. When you are totally comfortable and enjoying life.

You may not actually be asleep yet, but you're relaxed and have nothing on your mind.

2. When you spring out of bed and are super alert.

Granted, this doesn't happen all that often but every now and then, you either a) are really excited for what the day holds or b) have something you can't miss so you make sure you're up.

3. When you need a little more time to wake up.

Sometimes your alarm goes off but you don't really want to get out of bed just yet. So, you take some extra time to sit up, yawn, and stretch before getting up to start your day.

4. It's midday and you just need a nap.

Maybe you just took an exam. Maybe you were in the gym. Maybe you just sat through some fairly boring classes. Whatever the reason, it's the middle of the afternoon and you need a nap.

5. When your roommate is sound asleep and you're wide awake.Don't you just wish you could be them?

6. You really need a nap but there's stuff on your bed so you'll settle for whatever surface is available.You're so tired that the surface you're sleeping on doesn't even matter. Well, it probably will when you wake up but you can worry about that later.

7. Who dares disturb my slumber?There may be a time when you sleep through your alarm and one of your friends will come in to make sure you get up. You definitely be thanking them for it later -you'd do the same for them - but you probably aren't too happy now.

8. Contemplating whether or not it's really time to get up.Your head knows it's time to get up and get the day started but you want to stay in bed for just a little longer. So your mournfully look at the floor while gathering the energy to stand up and get the day going.

9. When you have an 8 a.m. class and didn't sleep well the night before.You're struggling to keep your eyes open and you really hope you aren't needed to answer a question.

10. I'm done.Everyone, student or not, has those moments where you're physically and mentally exhausted and you need to rest.
