an ant perceives the world as a flat plain,the have no idea of humans beside them even.to someone in the fourth dimension,third dimension is like a shadow is to us.so perhaps there is things happening we just don't see or attach a religious,or mystical reasons for it
We actually see in two dimensions, but our stereoscopic vision allows our brains to construct a 3D reification in our brain. Our experience of the passage of time (an artifact of mental processes) allows us to "experience" in a fourth dimension. But Physicists tell us they assume there to be at least 10 dimensions. We cannot grasp what the 5th dimension might look like, because our sensory apparatus is flat (retinas are two-dimensional) and isn't built to observe additional dimensions. But they exist, and physicists say that matter, space and time exists within them. Our natural senses are limited; this may explain why we cannot see touch or handle supernatural phenomenon. Or there may indeed be no such critter. Only time will tell.
The first three dimensions are spatial, the fourth is time, so watching something in action is perceiving all four dimensions. We are limited by our sense organs as to what we can see, so there is much more going on around us that we cannot perceive. Radio waves, from all the different radio stations and TV stations are traveling through our bodies. Billions of neutrinos pass through our bodies each second. Radiations of all sorts are happening all around us but we don't notice it. Our perceptual range is limited as well. We don't know what people are doing or saying in the house next to us, let alone in another country. Dark matter exists, but we have no idea what it is made of, and yet it makes up much more of the universe than our ordinary matter does. We could be traveling through it and not even be aware of it. Is there a fifth dimension? Possibly, maybe even probably, but there is plenty that we are not even aware of in just the four dimension that we are aware of now.
YES - there IS a lot going on around us we can't understand. Multiple dimensions are all theoretical and academic, so they have no practical part in your reality. Our eyes only see in two dimensions and our brain rearranges the signals to perceive three dimensions. Which is why so-called visual illusions are so common. It is easy to fool our eyes into thinking they see all sorts of things that aren't there. Electromagnetic emanations outside the color spectrum just aren't perceived at all. MOST of what is happening passes you by, actually....
