A dimension is a measure of the extent of space, and to understand it you need to be in the next dimension above it. 0th dimension: It is the state of a "point" in empty space, unable to express anything. 1st dimension: It's a state of "line" with an expanse such as "straight line" or "curve", and "time" also falls under this category. 2nd dimension: A "photo" or "drawing" is represented by an expanse of a "polygon" or "circle" that can be expressed with two coordinates, and human vision is processed in a "two-dimensional" manner. 3rd dimension: It has "width", "height", and "depth", and is a state of expanse with degrees of freedom in each direction. The world in which humans exist is "3rd dimension". 4th dimension: Although it cannot be perceived with human vision, it's a state in which an expansive direction created by arranging objects such as 3rd dimensional solids is added. And in physics, it defined a state in which is added "time" in "3rd dimensions of space" and "1st dimension of time". 5th dimension: It's added "distance in the 5th dimension" in "width", "height", "depth", "time", may also be expressed as a parallel world in which 4th dimension are arranged side by side. 6th dimension: Up until the 5th dimension, it was the material world, but from the 6th dimension, the spiritual world has also been added, and there is a boundary line where your spirit overlaps with the spirit of others. 7th dimension: It's an unchanging state where time does not flow, and the spirits that overlap in the 6th dimension are a great energy.
