What Do My Abilities Mean

my name is skyler and I'm 14 years old, every since I was little I have felt "diffrent" from everyone else. Even my 3 siblings I would often find myself being alone and into deep thoughts, and I never knew why. As I got older around 12ish I have started having dreams and I never remember these dreams of mine but, later on a few days later or so it can even be weeks i'll be standing somewhere and come to realize that I have been there before. Like a dej a vu kind of thing and I think to myself "ive seen this before. I have lived through this moment" at first I was like oh no its just a coincident but, it kept going occuring. Another thing I have started thinking about. Or realizing I should say is ill be standing somewhere and ill see shapes fall from the sky or something and there just shadows but ill just watch them. Reading on this site I have picked up, that this could be energy that I'm picking up or seeing in other words. Another thing in my abilities is ill see something happen right before it happens. Literally seconds before sometimes. But I never realize that theyre visions that I'm actually having until it happens. I think my gift is getting stronger though because recently about two years ago heading to my granparents house which was about half an hour away and I had this horrible gut feeling and I knew in my head that something bad was going to happen the thought of my mom was in my head and I kept questioning myself on if I should text her to see if everything was alright. But then again what if she thought I was crazy and I was just freaking out for no reason. That feeling was so unbearable that I started freaking out but all I could do was sit there and try and act calm. But as we kept driving it got worse and I thought that something with us was going to happen. When that feeling comes I think for the worse but its pretty suckish when you can't tell a difference between a made up thought and a prediction. When we passed over this bridge that was over a creek the feeling was even worse and then a vision of a van came into my head and it was the exact scene of what was going to happen that night. But I didn't know it at the time. So I arrived at my grandparents and everything was okay well the next day I was told what happened and it was someone who was close to us. I was explained to that she fell asleep at the wheel and wrecked off the bridge. The same bridge I went across the night before. I can't help but to feel a little guilty but I could of done nothing honestly. I mean that was the first time I had ever experienced it. I have a few more things that go to what I can feel. For example I can sense the way someone feels like it gets handed to me and I can't help but be down by it. If I have touched a person and said a few words to them I can later be sitting in my room and that person will pop into my head and I can feel their pain. I immediately text them and ask if they're okay. I don't want to freak them out either and tell them how I always know what they feel. Sometimes I can read peoples minds or I can look at a multiple choice answer focus then close my eyes and see the right answer get larger then the others. I don't even have to read the questions and ill get it right. Don't get me wrong though its not like I can ace tests because doing it takes a lot of focus and energy. I can sense energy in a room and I get it all. My memory isn't that good but somehow random scenes of my past will pop into my head and i'll watch them like a little movie I don't know how it works though. If anyone can help me to explain what all of this means please give me some advice. Thanks
