I can't sleep.

Sometimes Tinydog has to pee at 4am. He lets me know by sitting on my head until I wake up and take him outside.

You know when something is wrong, but you're not awake enough to figure out what? I've had asthma attacks and reflux in my sleep, and I usually spend an hour or more trying to figure out why I can't sleep before I become conscious enough to realize what the problem is and how to fix it.

Sometimes it takes me well over an hour to realize there is a dog on my head. I sleep pretty deeply.
