Bedtime woes

A couple of weeks ago, we were going through the standard bedtime routine, which generally involves carrying protesting kids to bed, then having them come out of their room for any number of made up reasons.

On this particular night, we actually convinced Rebecca to go in to her own bed (as opposed to Emily's bed, the floor in our room, or even the floor in the hallway). A couple of minutes later, she comes out with Emily telling us that she can't sleep because "there's this in my bed".

Upon further investigation, we find that she had puked in her bed the night before, and that the puke had now dried up on her sheet, pillow and blanket.

How you can puke in your sleep and not notice is beyond me. How you can sleep through someone puking in the bunk-bed below you and not wake up is also beyond me.
