Sierra groans. Groans loudly.

She would really like an answer to this.
She would really like it to stop happening.
She would really like to know where her clothes are.

It takes about ten seconds to find an answer.
Sadly, it's the answer to the third question-her clothes are in a small bag, as they have been pretty much every time. She seems to appreciate the courtesy as she changes-and even goes as far as to put the mysterious clothes she was wearing into the bag.

After all, confusing as this is, it always leaves a note for her. She may as well be polite back.

Dressed, with her belongings, she goes down, intending to get a drink to wake up with.
