[RPG] What do you see in a mirror when a vampire picks up an object

dungeons-and-dragonsmonsters

When a D&D-vampire picks up an object, what do you see in a mirror? With the vampire having no reflection (and neither his clothing), does the item float? Does it get invisible? Does it depend on D&D rules version and/or the setting in use?

"Real world" reason for the question: A PC sits in a bar with a large mirror, back to the common room. Would he see a vampire sneaking up to him that picked up a stool to smash it on the PCs head in the mirror?

There is no RAW for this, but with the intention of following the RAI I would look for similar effects already stated. Therefore I would rule that the effect of an Invisibility spell apply to the reflection of the vampire:

"If the recipient is a creature carrying gear, that vanishes, too. [...] Items dropped or put down by an invisible creature become visible; items picked up disappear if tucked into the clothing or pouches worn by the creature."

Within the limits of common sense, of course; for example, the vampire's reflection wouldn't become visible after attacking, making this actually a Greater Invisibility spell, and of course the effect cannot be dispelled since it is a supernatural effect.

The above description works for 3.5e; I am not familiar with the mechanics in the different D&D editions, but whatever happens to the reflection will be tied to what the game you're playing defines as being invisible.
