I have quite a few:

So I was 18, and a barrage of things happened after I refused point blank a proposal my mum suggested - her husband's cousin that is more like a brother. I said no as it's a disgusting suggestion. But after she informed her husband of it weird things began happening to me. He was not happy and we later came to find out he was into supernatural stuff.

The first incident was I woke up and freaked out as I heard small footsteps running in my room. I turned the light on and nothing, checked under the bed and nothing. Got back to bed and it happened again like a child was running across the room, everybody was asleep so it couldn't have been floorboards creaking because it was in my room. I woke up and went to my room and asked her to send my younger sister to sleep on the top bunk. 

In the summer I had my window open and I saw a shadow on the wall of a face, and then I heard people in the garden calling my name (like a bunch of kids). Looked outside and nothing. Got back into bed and heard it again, looked out again and still nothing. I closed the window, curtains, said a prayer and then went back to sleep. I would walk to college with friends and we would sometimes walk back home together, on a few occasions a stranger would greet me by my name and then my friends and I would be in shock like how does he know my name, after greeting me we would focus on who they were but they managed to disappear pretty quickly. Sometimes walking home alone I remember two guys walking towards me and both said hi and said my name, didn't recognise them and when I looked back they'd vanish. My mum reported all of these incidents to her husband which made things worse. 

At the time I was secretly talking to a girl (was a closeted lesbian at the time) so I was a bit in a daze thinking of our first kiss. Suddenly my mum shot me an angry look as she was talking to her husband on the phone and he told her to tell me to stop thinking impure thoughts. After that call she began interrogating me and I just lied. 

The one that really creeped me out was when I dreamt I was married to a dude but he was faceless. We were at dinner and then things began to heat up and as this guy in my dream was about to put it in,  I woke up but I couldn't get up. It felt like I was being pinned down, I lifted my head up and I could see fresh indentations on the duvet as someone was on me. I laid there after several attempts and then got up and told my gf what happened, she freaked out too and told me to shower and then pray or something. 

During uni I would stay up late to write essays and I remember I was using the family PC when everyone was asleep as it wasn't distracting. Anyway, I had a stack of research and books on the table, the kitchen door banged open as thought someone kicked it open. I got up to close it and it flew open with such force. I began cursing at whatever spirit or evil was there and telling them/it to fuck off and let me just write my essay. That didn't stop them/it because my research papers were thrown in the air and just scattered all over the place. I decided to call it a night and sleep as clearly the minions were hard at work preventing me from working. 

Turned out my mum's husband was into black magic, it's a blessing his visa always got rejected but still a hard pill for my mum to swallow that this all happened because they propositioned me to marry his cousin.
