Of course believing in the supernatural is absurd -- what does
that even mean? If, for example, ghosts were real, then this would
just mean that current scientific theories are incomplete or wrong.
That would just mean the terminology isn't very good. It would be
more accurate to say you do (or don't) believe in ghosts.
That's a good point.
Of course the non-materialist deals with ontological problems. Do
entities perceived under the influence of psychoactive drugs exist
in some sense?
At Iridia, there has been a talk and demo of Virtual Reality. I
have been very often disappointed, but this time I have been quite
impressed. They have solved the main problems, and the immersion
feeling was quite realist, in all direction where you looked,
without any screen border, and perfect real time synchronization
for any type of the move of your head or eyes.
Does this involve wearing 3D display goggles such as Occulus Rift?
Yes. I saw 'Occulus' written on the device, (but not Rift).

My son has created a video game, "Homesick", of the exploration/
puzzle genre, which will be available for Occulus. I tried out
their goggles and the experience is quite realistic in terms of
looking around. In a test at a video game exhibition many people
trying them could not bring themselves to step off a virtual cliff.
Wonderful! I really would like to buy such Occulus goggles, but more
to make amazing experience than playing game. But video-games is the
main accelerator in the VR field.

In one demo there was a creature, was it real? Those things are
relatively real. Like in personal nocturnal dream, or when reading
a novel, and with comp, like with physicalism, there is a physical
reality, which is a priori different from a machine (as it is a sum
of the work of all machine) "acting" below our substitution level.
In arithmetic, one virtual reality is less virtual than all the
others, as it has the "correct" comp bottom. That define a notion
of "physically real", and most entities perceived in inebriated
state are very often not physically real. But they might still be
images of important routine operating in the brain of a large class
of possible subject, and be entities living on alternate reality
planes, but still there by Turing-Universal + FPI.
Virtual reality might help people for the thought experiences, and
many (new) things.
But in the long run, we have to be careful, as the poor might one
day not afford visiting a non virtual reality. If we don't think a
bit, we might end up all in brains in vats.
