Base on true life story...
Me and favour have been dating for over 3 years now,, she love and. I love her, but anytime I ask of her parent she never seem to give me answers even when I told her about our wedding,, and I also notice she doesn't like mirror, all the mirrors in my house was broken to pieces I was not suspecting anytime I taught it was just a normal thing,, until one faithful night when I was half asleep I notice she looking at me at this moment I was scared don't why she is looking at me she did for good 3 days until one day I decided to tell my mum about her,, my mum was a prayer warrior immediately she saw her I notice some changes of moment and mood but i kept quiet that same night my mum ask me to stay in her room and I should not sleep so that night my mum start praying for me at 12 am to 3am during unGodly hour this girl came to my door and start knocking but my mum refuse to be distracted she keep praying and praying till it was 5 am by this time this girl have disappeared uptill now haven't seen her even her cloths too gone ,, my mum now told me that she was a mermaid that want to take me to her world so I can be her husband,, but the prayer of my mum saved me....
