Defining Alternate Reality

The internet defines an alternate reality  as a parallel universe or a multiverse.  An alternate reality could be a universe of where all the natural and /or physical laws are different and has no limitations.  It could be a universe where gravity is non-existent  on earth.  I believe an alternate reality could be all these things but an alternate reality is what you want it to be but something that is not part of daily reality, or daily reality in a new and different way.  It could even be you as an evil "twin" or a personality that you wish you were.  An alternate reality has so many possibilities and leaves room for creativity  and to make of it as in any way you wish and do so please.
