For a long time, I simply thought that Dumbledore meant he had learned
to walk and breathe so silently and, well, motionlessly, that he was
unnoticed. Biologists observing animals in the wild often report never
seeing their animal, only its tracks and scat and kill sites (if a
predator) because it can walk right past them without being seen
because it blends in so well with the scenery.

However, there IS that"Invisible Book of Invisibility". It seems to me
that the only way it could have been a hoax/joke, taking advantage of
being invisible to also be blank or mostly blank, would be if BOTH the
author and the publisher had that kind of humor. So I prefer to
believe that there was an entire book written about invisibility,
which strongly suggests that it would mention more ways to become
invisible than an Invisibility Cloak. Surely the Snape fans would be
delighted if their idol had invented the first reliable Invisibility
Potion!
