From 3 dimensions to 5?

Are we really living in 3 dimensions...as we are told? Our reality is what we are teached about, yes? At least for me it makes sense. My world is what it has formed during the years of education, experiences, media and so on. When i do art, i often feel like im creating something that is existing beyond what i can see, what i can sense or what i "know". The weird feeling that there is more...it`s called imagination. For some it`s just too much imagination, for some imagination is bigger than knowledge (Albert Einstein). I magination, the reality in ideas world takes over materia ( so called 3d). Quantum physics has been known already long...why not then 5d? More and more im aware, that we are more as human beings than 3d, that the reality consists of so much more - which is beyond the visible world. That`s to live in a diverse world!
