First Paranormal Experiences

When I was around 12 or 13, and I first moved into the house I live in now, I glanced out the window and saw three people dressed in clothes from the 1800s, which I thought was insanely weird, so I told my stepfather there was someone coming to the door, he looked out the window, and they weren't there anymore. I just brushed it off, thinking that it was just my imagination, or I was over-tired. A few weeks later, I glanced out the window again and saw the same three people walking up the driveway, I brought Craig over (my stepfather), and he told me he couldn't see anyone, and I still could. I never told him that, because I was terrified he'd think I was crazy. I saw them a couple more times before I told my mom, and she immediately asked what they were wearing, I described the girl with a little bonnet on, kinda chubby, holding a mans arm, dressed in an old suit, and a man behind them, watching them, seemingly lonely. Described the clothes, etc. She told me when she was my age, she would dream about people that looked exactly like them. Then everywhere I went, I'd see something out of the corner of my eyes, feeling like someone was watching. Once when I got kicked out of my house, I went to the park nearby, and it was really dark. across the street, there was a really creepy man, and I could tell he wasn't really alive. it's just this feeling that you get like someones there, and for me, I don't talk to them, but if I ask a question, I just feel the answer. anywho, that's the only spirit that creeps me out.
