For a start, floating might be really fun, but what else might you get up to?
Iβll play but what are the rules here? Can I move objects? Do people hear/see me? Ooh, can I possess people?
Letβs suppose basic ghostly/poltergeist capacities, so nothing on the level of a great spirit or deity, in which case basically yes to what you mention (and in similar ways, so the whole hearing/seeing would be something you could flip on/off, make a case by case to mess with folks, etc.).
