I have been reading experiences on this site since a long time and have been a member since last year I guess, but this is my first story.
This happened back in 2012 when my step-Grandmom died. It was couple of days after her death and I don't know if it's paranormal or not but I am sharing this just to see if anyone had any similar experiences or have some light to shed on it.
At the time I was staying with my parents and me and my sister shared the same room. I woke up in my dream unable to move or make a sound and I thought maybe it is another case of sleep paralysis since I somehow knew I was in a dream and I read about sleep paralysis at a lot of sites (the scientific approach), but as soon as I woke up or I thought that I am awake, I saw my Grandmother standing next to my bed and asking me to come with her and it was not a polite way of asking. I literally felt that she is about to drag me pulling at my hand and I started struggling. My comforter was pulled off and I started screaming which was coming out as mumbling. That is when my sister woke up and she heard me crying and sobbing in my sleep and woke me up by shaking me.
Now why am I confused if this was just a dream or if it was real is because I had a little ache in my arm, the way you get when someone pulls you by your arm and my comforter was pulled away. I know that the position of the comforter may be because of my movement but I cannot understand the arm thing.
I didn't have a bad relationship with my grandmother, she was not a bad person, she was my father's stepmother.
PS: I had researched about sleep paralysis because I used to get those a lot during the period between 2009 and 2014. It used to leave me really scared initially and I started researching about it on internet hoping to find a logical explanation which I did but there are still some more cases of sleep paralysis with me that are not at all logical and I am hoping to share it with another post sometime.
