Well... then you re-discovered by yourself some very ancient teachings... in occult, we learn that the universe is composed of "planes". They are not planes in the usual (or mathematical) sense of the world. They are more like the layers of color in a coloured picture... like... a coloured picture can be separated in a layer of reds, a layer of greens and a layer of blues. The sum of this 3 layers give the complete coloured picture. This is the process used to transmit images in the TVS, DVDs, and etc.
So, the universe is formed of (traditionally) seven planes, and four of them are accessible to us humans.
There is the physical plane, where the physical matter exists, the "astral plane", where the emotions exist, the "mental plane", where the thoughts exist, and the "buddhic plane", where deepest things, like mystical insights, exist. The other three planes are beyond the normal human consciousness.
