Do our senses lie?

How can we so sure what we see/hear is real? Why is Newton watching the apple drop real, and people having out of body experiences not real? At the end of the day, all we have to decide what is real is the information that comes in through our eyes, ears, nerves, taste, smell etc. If we didn’t have olfactory (smell) senses, would we say that there is no thing as smell? If we were colour blind, would that mean that there is no such thing as colour? Suppose that we are missing a sense that would enable us to…………….fill in the blank. It is very difficult to think of what this new sense might be, because it is very difficult to imagine another way of perceiving the world. But that doesn’t mean that there aren’t other senses, just that we are not privy to them. Animals often hush and hide just before an earthquake happens; does that mean that they have a sixth sense we are not aware of, and that we will never be aware of.
