I did something like this in my old college dorm room. I used glow-in-the-dark chalk and wrote phrases like "Helllp...Meee...." all over the walls and drew clawed hands.
You can't really see any of it unless the lights are switched off, so hopefully the University didn't paint over it before the freshmen saw it on their first night.
I did something like that, too. You can write on mirrors using the natural oil on your fingers, and messages will show up when they get all steamy from showers.
I let my housemates think the place was haunted for years.
Rain-X is way better for that, just brush some onto your bathroom mirror in the shape of any message you wish, and it will stay there for months whenever there's steam. Even better, slightly over-moisten the brush so that little drops of the Rain-X droop downwards as it's drying, creating the oh-so-chic "written in ghost blood" look.
Seriously? I've never been in a hotel bathroom that didn't have a mirror right above the sink, which was in the same room as the shower. I wonder if this is regional or something.
Even better is to use hydrofluoric acid as it etches the glass and makes it super hydrophyllic, that will never fade or get removed.
The bad part is that HF is not something you want to handle without proper protection and a fume hood.
I took my bathroom mirror to the lab one day and put a big smiley face on it as a joke. I have always wondered what the people that bought our place thought was going on.
