What Would You Do: Idea Hits After You Close Your Eyes to Sleep

I don't know if this is a feature that will stick or not, but I'm going to try thinking up different writer-related scenarios and see what everyone thinks they'd do in the situation. Of course, whether this feature will "stick or not" depends on whether people comment below. If it sounds like fun to you, please don't be shy. Share your thoughts!

Pesky ideas--waiting until after hours to strike!

WWYD Scenario #1: Idea Hits After You Lay Down for Bed
You know the drill. Perhaps you've had a stressful day and the writing well has been dry for more than a week. You're not even worried about it though, because you've brushed your teeth, taken out your contacts, and slipped into your jammies. In fact, you've already turned out the lights and are snuggled in tight to your pillow.

And then, bam! The perfect idea for a story or article slams you upside the head. Or the perfect line for a poem trips up the sheep you've been counting so diligently.

Now, what would you do?

Do you jump out of bed and proclaim, "Eureka!"? Do you try to scribble something in the dark? Do you think to yourself, I can remember this until tomorrow morning? Or do you just try to ignore the greatest idea you may ever have?

Please comment below to let me know what you would do. The only way this will be fun is if people participate, so I'll leave a comment (or two) below as well.
