Falling Asleep

There are those who fall asleep
As soon as they’re in bed.
Other people toss and turn
Or count some sheep instead.

If you’re lucky, you’ll be out
As soon as there’s no light.
Others rarely sleep more than
An hour every night.

Have much sleep you really need
Can vary case by case;
But when you do not get enough,
It shows, right on your face.

So nighty-night; I hope your slumber
Comes real quick and deep;
And may you have a lovely dream
To keep you fast asleep.
