scene in dream is a mirror image of the real world

[littlebirch]

Hello everybody!I'm a newbie of Psychology Forum.Actually,I have exprienced quite some events which is strange for me.I start the first one here,for some years,sometimes when dreaming,the scene in my dream is a mirror image compared with the real world,I mean,the relationship of position of left and right,quite like what I see the real world from a mirror.Is there anyone have experienced such event?or if there is any theory to explain this event?
I'm glad to see your reply!
