5d, 6d, and 7d are all dimensions in the living world. the 7d we can not see because it is beyond our comprehension without the use of computers(exp. the matrix). the 5d is having the 5 senses working at the same time as seeing oneself(3rd person shooters exp. call of duty). 6d is seeing past, present and future and how they affect you or others(exp. touch).
