A dark figure in Ontario

This must have been over a year ago. But it's happened three times, a little differently each time. I'm lying in bed, and I feel a presence. The first time I felt something on my left. I knew it was a swirling dark figure, though my eyes were closed. I could feel it, the air was heavy, like there was no movement in the room. This is odd, because I always sleep with a fan on. But I heard no noise and felt no movement, the air was still. I felt incredible pressure and intense fear. The only thing that worked was prayer. The moment I prayed, I saw it leave out my window, in a flash. Then I fell asleep instantly. The second occurance was the scariest. I felt someone in my room. I was certain it was my mother, as she has been known to check if I am awake or sleeping. (and nowadays, looking to see if my cat is cuddling with me) I didn't think much of it, as I trust my mother completely. 'My mother' put 'her' hand on my shoulder. I thought that was peculiar. It felt a little heavy and maybe a little cold. But solid, real. Why was she here, doing this? Then the hand moved, it shoved me. It pushed me into my mattress, and I moved. As the hand pushed me, it started to almost phase through me, the pressure lifting off. I was taken with a horrible sense of fear, I felt the air grow heavy again. Prayer was the only thing to help me. The third instance was the least scary, though bizarre. I woke up early in the morning, I don't know why I knew it was morning. But I felt a sense of weight, and the air was still again. There was a presence in my room with me. But there was the sound of, almost, drilling. Like some kind of high pitched screwdriver in my ear. There was pressure in my head. In my half-conscious thoughts, it felt like something was trying to get into my head. I tried to pray, repeat the Psalm the Lord is my Shepherd, anything I could do to get it to go away. It slowly receded, leaving me panicked and slightly shaky. I know when someone is in my room, as I feel their spatial presence. When my mother checks on me, I feel her before I open my eyes and see her. Once I thought I was having an scary encounter, as I felt a strong sense of presence and being watched...until my cat hopped up to say hello. Silly beast. But these instances were before I had my cat. My mother never left her bedroom to come into my room, I confirmed. I feel a bit insane for saying I felt presence, but I did. And my father can confirm he has felt something floating above him, with presence. So I feel less alone, though still confused.
