We have way more than five or even six senses, so this whole thread is kind of meaningless. However, there's nothing supernatural about it.
People who know their way around places they're familiar with are just using a combination of memory and proprioception, along with other tertiary senses, such as detecting air currents and heat and cold to associate your location with common things like doorways, windows or vents. It's an adaption that a lot of people have, but there's nothing supernatural about it.
The same goes for people who can detect people around them. We all have definitive traits to our actions, even if you think you don't. If you know someone really well, all you often need is to hear their footsteps to know it's them, consciously or not. Again, impressive, but far from supernatural.
Knowing what people are thinking or feeling doesn't make you some mystic or mutant. It just means you're a well-developed person. Actually it's funny, because I guess a lot of hardcore gamers and other like shut-ins think this is some kind of weird ability they or others have, but actually must well-adjusted people have it. It's just empathy. It's reading body language and vocal inflections and tones to detect emotional levels. The more you know someone, the easier it is to figure out how they're feeling. The more someone is aware of their body language, the harder they are to figure out. That's just human interaction 101.
There's other examples of this too: Women who live together for a long time having their cycles becoming in sync, or twins, couples and best friends being able to finish each other's sentences(I can do this with my best friend, and while bizarre and impressive, there's nothing supernatural or otherworldly about it). These are all things that we naturally do as we become closer. It's just biological adaptations and it's nothing new. As people grow older they may become more aware of it or as they start getting out more they may start to just actually experience it and not understand it. As a result, they make shit up. Same reason why pretty much any non-scientific bullshit is created. Also people acting strangely on the full moon. Nothing supernatural about it. We're mostly water and built to be in and interact around water, so it's not surprising that something powerful enough to create the tides has an impact on our brains. There's a scientific explanation to everything, even if we don't know it at the time.
Hell, some people who work with in or with electrical fields frequently are able to detect changes within the field and know instinctively to flee when things are going badly. How? They can feel the changes with their body hair subconsciously(or consciously, if it's a trained ability and not a naturally developing one).
For those of you who don't believe or understand how we can have more than five senses, close your eyes. Touch your nose with your hand. How did you do that? You can't see your hand or your nose with your eyes closed. You can't feel your hand and your nose together until they're already touching, and I seriously doubt you used smell to guide your finger to your nose(if that's the case you need to shower, badly). No, you used a sense called proprioception to guide your finger to your nose. It's the sense of knowing where your body is relative to itself. It's how people juggle and a big part of swimming. People who have "out of body experiences" are actually just having severe neural misfires, and their proprioception and a few other secondary senses are all out of whack for the same small moment of time. For people who have "precognition", you have a subconscious dependency on your intuition and some very minor brain damage: Your brain is storing events that are happening right now further back in your memory, causing you to "recall" them as if you've seen them before. I get this a lot too. Some people call it Deja Vu. I wish I actually did have some kind of wacky ability to see the future, but it's really just a neural misfire.
The human body is weird, wacky and wonderful. It's got all sorts of tricks and there's still so much we don't know. But the unknown isn't magical, mystical or spooky. There's no Arcane, no Spiritual and no Comic Book style Mutations. It's just us being the regular old biological anomalies that we are.
I mean really, who ever heard of the mostly hairless semi-aquatic translucent pink chimps roaming around anywhere from the heart of the desert to the deepest jungle, climbing the highest mountains and checking out the bottom of the ocean? What kind of crazy animals are we anyways?
