This is my first time posting on here, so please bear with me.
I don't really know what category this would fall under, but here it goes. About three years ago I was living at my grandparents' house (well mobile home to be exact). This home belonged to my aunt and uncle when I was a younger child. It later was bought from my uncle after his recent divorce from my aunt.
The couple that occupied the house for a while had this creepy feeling about them. You know how when you're a kid and you can just tell when someone is just not right to be around. Well, anyway, they later moved out of the house and my grandparents bought it and let my father and his wife rent their old house.
Anyway here is the experiences. In my bedroom I was laying down sleeping when out of nowhere it feels as if someone sits on the opposite side of the bed (my bed was whichever size is just above full, a queen I think). I instantly stayed still, too worried to move, when next I feel what seems to be a hand rub my hair. (It felt comforting.) Once I gathered up the courage to roll over and look (knowing in my mind that both my grandparents were asleep on the other side of the house) I saw nothing. The rest of the night was free of anything out of the regular.
The second experience took place in what is the "spare" room, also used by my younger brothers (and I do mean younger, currently ages of 4 and 6 years old). I went to sleep in there real quick due to it being the brightest room in the house and it was mid-noon at the time. I was asleep for what felt like an hour. I was laying there on my back and next thing I know I can't move and the sheets feel as if they are constricting me. I can open up my eyes but I cannot speak a word, not even gargle. I saw nothing but felt very cold, and for being under four comforters seemed extremely weird.
The third experience (this one bothers me the most). I was helping my grandparents watch my younger brothers when at one point they went into the "spare" room to play. Then I heard the door slam. I thought nothing of it at first seeing as how they are young and love to slam doors. Then I hear the youngest one crying and the oldest screaming "NO!" I just thought they were fighting over a toy since all their toys were in that room. So I got up to intervene, but I couldn't get the door open and none of the doors except my grandparents' has a lock. I then said "If I have to come in there, boys, someone is going to be in trouble!" and right the door was released and I was able to get inside and saw straight fear in their faces. They never told me what happened.
If anyone has any idea as to what could have caused any of these please let me know. I am also pagan and am open to many answers as long as they are not completely ridiculous.
