Can Tragedy Cause Psychic Awareness?

I'm not sure where to even begin. I grew up in a religious and sheltered life where ideas such as "psychic abilities" were strongly discouraged. Most of my childhood and teenage years were uneventful. A year and a half ago though my husband rocked my world by nearly killing our child before taking his own life while I was at work. I'm only mentioning this because I feel that it changed (or possibly developed?) me. Since that day I have had quite a few experiences that "rattled" me.

First off, I've slept-walked multiple times (even drove to a gas station while in such a state). I NEVER did this before. In many of my "episodes" I would be roaming around the house and see someone standing in front of me. Sometimes it was someone I knew, sometimes it wasn't. I would approach these people fully believing that they were there, only to have them slowly fade away as I got closer to them (my injured son was the person that I saw the most). I also have had many experiences with sleep paralysis. This HAS happened to me before in my youth, but not nearly as often as recently. The last one I fell asleep while my boyfriend was playing a video game next to our bed. I remember thinking that I needed to get something from downstairs and tried multiple times to get out of the bed, only to realize that I couldn't move. I tried asking my boyfriend for help but it seemed as if I was incapable of speaking. It always frightens me so I have not been able to have any out of body experiences.

The other thing I want to talk about is that I seem to have developed strong intuition. Some things are minor, others are major. The minor things include things like KNOWING that someone has lied to me, even KNOWING the TRUTH before I find any evidence to prove it. Or knowing that my boyfriend will be going out with a friend that night (which he doesn't do very often) before he even says a word to me, this was quite a shock to him and he couldn't figure out how I had known. I can sense people's moods before I even see them, which to me isn't hard at all. My mother has been startled many times by me when I will call her the very second that she thinks of me (she has told me this). The more major incidences are things like when my Grandma died. That day I took my kids to get their haircut, everything was fine but when we left I suddenly felt the most incredible feeling of dread and panic (this was at 12:30). I had no idea what had caused this but it didn't end. A few hours later my dad called and told me that my Grandmother had a heart attack that day and had died within minutes. After the shock of this I called him back and asked him what time she had died and he replied "sometime between 12:30 and 1:00".

The reason I'm taking the time to write all of this is because in the last few days things seem to have heightened (the story about my grandma was 3 days ago). A few days ago I was talking to a friend who is also highly intuitive and even reads tarot cards. During our conversation he told me that he could see "dark forces" around me. While I was unnerved, I was not surprised because I can feel them. Today I had the most undeniable experience. I was watching a movie when suddenly I had the most detailed mental image (or vision?) flash through my mind, it lasted about 10 seconds (I don't want to describe what I saw because it was quite graphic in nature). Then a few hours later the exact same thing that I saw happened.

Due to my personality type, or possibly upbringing, I find it difficult to talk about these things to people that I know because I worry that they'd either brush me off, or think that I had lost my mind. I would really appreciate anyone's incite on these events, or if someone else has/had experiences like mine I would love to hear about them because I feel very alone in this sometimes.
