Riley Found a New Dimension

Imagine sleeping and waking to a crying child.  You are groggy and not quite all there.  Then, while attempting to comfort the child, you find that she is not in her bed.  You look under the bed, she is not there either.  You call out for her and she is shouting, "I am under the bed." 
"Where?"
"I am under the bed."
"I can't see you."
"I am trapped."
Apparently, she was so tiny, she fell through the top head space and fell through the frame, under the couch.  The odd thing was, she couldn't get out.  Her head was too big to climb back out.  Somehow, she mustered enough pain tolerance to forcer her head through. I don't know how she even got in there, but I am glad we did.
