You decide that it'd be too dangerous to try anything other than contact her. At your size it'd be extremely difficult (not to mention dangerous) just to get to the floor- then, you have no idea where you are. She could live by herself and you'd have to trek possibly miles before you could find another person. And then you wouldn't probably have another chance at one that's calmly sleeping and easy to approach. That's not even getting onto how to get people to notice you from the ground. No, there were just too many things that could go wrong. This was your best chance at being noticed.
You take a few deep breaths and begin to mentally prepare yourself for what you're about to do. You want to do this right; with just a flick of her foot the wrong way she could squish your frail little body like a bug under her pretty sole without even waking up.
Gulp.
How did bugs live like this again?
Running over a few choices in her head, you decide it'd be safest to get attention from your current location- it'd be easier for her to notice you near her face, but it'd take too long to trek, and there's no body part more sensitive to irritation than the bottom of feet. So you could tickle her foot, hope she wakes up and doesn't just rearrange herself- possibly rolling her feet on top of you and squish you. Or think you're a bug in her drowsy state of mind and do flick you off her bed, possibly breaking all of the bones in your body.
Ugh.
So when she wakes up, jump, scream, do whatever you can to help her identify you as a tiny person.
Taking another few deep breaths, you look her up and down again. From your current location, positioned a few feet (from your perspective) away from her feet (which were conveniently just barely sticking out of her sheets) and between them, you could just barely see the rises of her body under her bed spread in the distance. She was unimaginably huge compared to you, her big toes almost as big as your entire body. You can just the slightest glimpses of her face, uncovered by her blanket and propped up into vision by several frilly, large pink pillows. You couldn't see much, but you could tell she was as pretty as she was big- flawless features and soft, smooth, feminine skin. For a moment your heart skips a beat.
Great. Pretty girls are already intimidating enough when you're the same size, now you're dealing with one that's a hundred times your size. Sigh. For a moment you appreciate every average, approachable girl you've ever met in your entire life.
Taking one last deep breath and one last run over of your plan in your head, you approach her delicate, and proportionality dainty but, from your perspective, massive foot and place your hands on her soft soles. Closing your eyes in concentration and nervousness you push in further against her plush skin and begin rubbing, hoping to stir sleeping beauty.
