If you let me bite you, the bite to me
the physical pain of bite to you
the feeling and thought of bite for me
the mental feeling of pain to you
when walking on the street I saw my friend cross the street, she is real to me, but my friend didn’t see me, so I am not real to her. (same moment, same existence, one is real, one is not) I am real to myself always, my body, my thoughts, my feeling, my spirit and soul are all real to myself.
some people consider that future is not real, Past is also not real anymore. they are gone. only the present time is considered Real.But then how to define the present time? in hours, in minutes, or seconds?
everything happened in your past can be real still because they were installed in your memory, you safekeep box. But if you forgot some, then those you forgot are not real to you any more.
