You opened your eyes, and are pleasantly surprised.

You opened your eyes and looked at the time.

5:58am

You woke up 2 minutes before your alarm.

This whole time you didn't realize it but you've been asleep the whole time.

But for how long?

There is no way for you to find out, but you can only guess.

But what was it that kept calling you to open your eyes?

The only way to find out, is to go back to sleep.

But that is for another night.
