My Experience Seeing Ghost And Things I Shouldn't

When I was about 6 years old my family and I moved into a house with upstairs which was a big attic that was turned into a room. There was one bath, and a big laundry room. When we first moved into the house late at night, we were all tried and went into the room that my parents pick out for them to sleep in. And it was cold so we had everyone together in the same room. I woke up in the middle of the night one the same day and heard voices above my head and I heard it loud and clear. The voices I heard were "Shhhh, their sleeping. Let's talk quietly. Stop she's a wake" I saw a smoky shadow above me and the voices didn't sound right. I went back to sleep after that. A few years passed and I was 10 and I moved up in the attic because it was my room. It got cold at night in the winter and got hot in the summer. And one day I got ready for school and in a glance of an eye I thought I saw my sister near the wall to my dresser while I was changing. "So what are you going to wear?" I had asked her. And I looked back and for one sec or less I thought I saw a little kid that was around my sisters age and I just swear that I just saw them standing right on the wall and then sitting down and puff there gone in a blink of an eye. I was thinking, I am just seeing things. So the next year came by and my dad made a closet because we didn't have one in the room to hang stuff. It was late at night and I hopped on top the closet. And looked out the window. There I saw a shadow behind the flag that was hanging outside the window.
