Ι've seen limbo/pre-incarnational dimension and humans were clearly segregated from reptilians. You know the people you meet, even the people you don't click. Events from there, are rough representations here, so that you may connect at all times with what you're going through 'there' even though linear time here makes it seem that limbo is past.
Why would someone need to remember all that? Why would someone want to incarnate as human at all?
