Do I Have Powers Or Am I Just Crazy?

I am 16 years old and I've just recently started to realize that something weird is going on! Well for starters this happens so frequently without fail that I've started to notice it more and more, whenever I think about a person even if I haven't talked to them in awhile or would have no reason for them to talk to me. I get a text message or phone call from them literally seconds after. I believe that I am somewhat sensitive to spirits because I was recently with my mom looking at a house to rent and that house happened to belong to one of my aunts friends that died in the house. The next day I woke up and saw a man standing by my bed. For some reason I didn't see his face I just felt his presence and saw a figure. I don't know how to describe it. But I didn't think "ghost!" at first I thought he was a real guy. Until after 30 seconds of me staring at him he vanished in thin air. I also get very strong vibes from people and I always seem to know people before I meet them and if I look at people I can sense

Their personalities and struggles. Sometimes I get really bad vibes about days like I get a feeling that something might go wrong so much that I do what I can to convince my friends that we shouldn't go out. I also want to know about angels and stuff cause I feel like they are giving me signs like within a month period one of my good friends almost died by cracking her skull, and another one of my

Good friends became pregnant. Is this a warning to be more careful? I know I don't have any remarkable powers but I just want to learn if I can develop stronger spirituality and grow spiritually. Or do I just have a super strong intuition? Or am I over analyzing everything? Oh and I also get really weird vivid dreams also a few of them I saw my dad die and I saw him embodied as a snake smoking cigarettes (because he smokes) and then the snake died. My dad is still alive though I just feel like it's a warning.
