hypnosis is very real.
also many other weird things.
*watch the uri geller show, freaky shit there*
Hypnosis isn't a sense and if you watch Uri Geller a bit more closely he really sucks at sleight of hand. Just saying. It was that or make a joke about The sixth sense being an alright movie and going "oh wait".
Anywho, you haven't told me what you mean by sixth sense aside from something vaguely approaching the description of a 'gut feeling' which I consider less of a 'sense' as an instinctive conclusion based on input from your other senses. If for example you walked into the same room with your eyes closed you probably wouldn't have gotten any feeling of 'bad news'.
Similarly 'sensing doorways and walls' is called memory. as in I'm familiar with this room and can vaguely estimate the location of solid objects within it due to having seen it.
Again, walk into a completely unfamiliar room with your eyes closed and then try sensing the furniture.
If you're referring to some form of telepathy and being able to glean thoughts and feelings from the minds of others using means undetectable to any form of medical science, then I don't believe that either. The human brain has no structures that resemble transmitters or receivers of any form of electromagnetic radiation such as radio waves, the skull insulates any bioelectric field it does produce and no accounts of psychic abilities follow any of the laws of physics, such as distance based falloff or being able to be blocked by dense objects.
Compound that with the fact that if something was happening we would certainly be able to detect it, build our own receivers or at least form a theory that predicts it's existance.
The fact that every so called psychic who ever lived has either been shown to be a fraud or has refused to be tested does not give me confidence in such a phenomona's existance.
Even if one of them was a psychic, they all follow methods indistinguishable from stage magic techniques (such as cold reading and sleight of hand) and nine times out of ten an honest magician can do them better, meaning that any effect that there is would be utterly useless in any practical sense.
Finally it makes no sense from an evolutionary standpoint - we don't see chimps having the beginnings of telepathy, and if it was a real trait, it would provide significant evolutionary advantage and large numbers of people would have it. we'd also be able to track the gene's progression geographically via it's frequency of expression and all that cool stuff.
In summary, no, there's no as of yet undiscovered 'sixth sense', psychic or otherwise and there's no plausible mechanism that could explain it's existence and that is also compatible with the laws of physics.
