no it is not from movies or something none of them. Just bad dream.
When I was 11 yrs old I was sleeping and it got bad dream that when I walk and look at mirror that I can see there tiny fire that can walk and talk in swimming pool in junior school and high school ECD then fire pull me into the mirror then all the fire tried to push and pull me to fell off into the swimming pool and I woke up and scream!!!! so my night counsellor Ryan (lady) came to me and take me to the living room to give me orange to eat then back to bed it was ok now then next day again bad dream and then I went to living room to ask my other night counsellor Marshall but she said NO! go to bed!!! so I go back to bed and still bad dream till finally stop bad dream then next day again again again I hate it. then in high school I leave the door open at night time not want close and see that mirror at night time near my bed in residence. my Grandmother have mirror so i cover. one of my friend have huge mirror and I was trying to ingore it and go sleep didnt get bad dream.
When my ex boyfriend moved to live with me and he took his mirror out of the box and put in my bedroom so I told him take the mirror out! of my bedroom and he refused listen to me so I cover it with the towel not want to see it then later on he woke up and go to washroom or kitchen that he took the towel off and it got me bad dream in few times in 2 or 3 days so I told him take his mirror OUT OF MY BEDROOM@!!!! it got me bad dream so he took his mirror into my kitchen to put on the wall to hung up.
That is why I just got bad dream from mirror in bedroom at night time. I rather mirror in living room or washroom that is all no bedroom
