It all started when my nan passed away 2006 I saw a few black dots at the corner of my eye, my mum and dad saw the same but in white. After a year or two passed I got over grieving but still saw these dots,then one night I saw her my nan I freaked out but it never felt like her, it felt evil and the dots became more a shadow and surrounded me everywhere I looked, mainly in the afternoon I then was very scared. I was scared and felt insecure and like something had been watching me for months and I was drawn to watching more horror films. Then started hearing things like I could hear what I can only explain was like the devil laughing at me and couldn't sleep, the more feared I was it grew on me. My mum prayed for me and I seen the word saved in my mind and then everything stopped I was telling myself nothing can scare me or harm me and the more confident I got it all stopped.but when I went to live with my fiancŽe something had changed about me. Their was a time he was going to see his dad and told me goodbye and went, but I herd someone or something walking in his room I turned and he was sat their I shouted him but no response, once he came home I asked him why he never replyed to me when I spoke to him he told me he never came back after he left. Few months later we were sleeping I woke up to turn over saw he was a sleep but he had his arm in the air so I went to put his arm down and it disapeard and it wasn't him all along, more months went by and a simlar thing happened again only bigger this time. When I turnd around I saw him sleeping but yet again I saw him but faintly walking around his bedroom looking for something, he walked towards himself and disappeared. Its not happened since.
I just want to know what it was that was/is happening to me and what it was I were seeing and what was drawing me to evil things. Can anyone help me find out?

Demonic forces are what draw you to evil things. These spirits may have seen the grieving of your family loss as a weakness and moved in there... the desire to watch horror very well could have then given it more of an open door into your life. This is how they work... they move in what a little entrance and begin to get more and more of a foothold in your life.

What is going on is nothing more than demonic spirits trying to manifest in your life.

I like that you saw the word "saved" in your mind when your mom prayed for you. That's a path you should get back on.
