MIRRORS!!

I was just wondering about mirrors and refection i mean how was it made and who invented it i will research that later so now i was thinking what is beyond the mirror and what if the mirror has another world behind it and our reflections are the guardians or the things blocking what ever is in there maybe dark scary horrible world and the mirror are the gates. But what if it is the other way around and we have the scary horrible world and the reflections are blocking our world from entering theres I guess we will never know so share your thoughts and leave a comment and suggestion and have a nice day,
