The reflection

this has to do with a dream I once had. I felt like something was watching me and I noticed weird things happening and i was with my boyfriend who was beside me and my mom was with me in the house too and as soon i look away i noticed this...white thing suddenly run into a mirror or ...my balcony i geuss and i head there and its dead midnight and i noticed i see my reflection and then theres something written in mist saying "when you see me,look back" and i look at my reflection more and it distorts into something else...him...big black eyes and he had no other features only that,and he held a knife and wore dark clothing,like a typical being i suppose...but i turned away and paniced and my lover had noticed that and as soon as that happened i heard..my closet door in my room just burst open and something racing out of my room down the halls and i head for the door with my boyfriend and he lifts me up  since i was pretty weak at the moment and when i look back i notice it was the demon humanoid being chasing us and my boyfriend just continued running until we were out of reach...and i woke up and just..something so real like that really surprised me
