.wtf 4D

Can u understand da followin-
Four dimensions are supposed to be da three dimesions of space + time.
Except in present day 4D theatres n shit where there is the shitty 3D effects, with shitty physical aspects combined which is considered da 4th dimension. U losers! What kind of a sad excuse for four dimensions is dat? Where I truly belong, in da future, we actually experience da movie dat we're watchin :) In mi time, we're now developing a technology where the movie actually consists of a preset number of certain points in time (da true 4th dimesion) that the film-makers produce PLUS what da observer creates for customised movies. These only have da common elements that the film-makers have produced dat different peeps share. So da movie dat we watch is the same, but we create it differently in certain parts are which are unique to each observer. U get mi drift? If not, I'll blog about that in the future, which to u is mi present, but for now,
can somebody please explain to me what this is in normal-ish language?????
