This is an experiment with negative visual hallucinations.  A positive
visual hallucination is seeing something which isn't there.  I've
experimented with both.

I've never had a case of visual negative hallucination similar to the
case described (.i.e. able to see something hidden behind the Invisible
man  :-)

I have hypnotised a suitably deep subject and "removed" an object from
the visual field (e.g. subject doesn't see a stool in front of them).
If you then ask them to walk across the room, they should trip over the
stool. Invariably, they step around or over the stool.  This is not a
test I routinely do :-) since I think making a person fall on their
face is a rude way to bring them out of hypnosis; consequently this may
be a case of proof by selected instances.
