My cat

 When you're lucky, you get to go back to sleep after waking up in the morning and get a few hours of lazy dream time. That sleep can be so delicious. 

But with certainty, I will have weird content, unpleasant dreams. Not super unpleasant, but those have been the ones I've woken you from crying, for example, or have given me thoughts that linger with me all day. I needed the sleep this morning, stayed up too late too many days in a row, but the dream was a sad one.
