Has anyone heard of Leonardo Da Vinci school in sacramento being haunted?

Well, what really scared me was me and my friend had the same ghost story that happend at this school. We both saw a woman in the middle of the summer time walking and then dissapear. When we both figured out that this had happended we were at the school alone we kept on seeing shawdows that had dissapeard into the walls. We go to this closet thing that keep's clothes. I look in through these small windows I see a head that was scared up pop up and scoot across the room. I tell my friend we should leave instead she look's in there and she see's something hiding in the corner. So were sitting near the gymn we see this boy he look's like he's in about 8th grade I say hi he has his hood on and both me and my friend's stomach feel's very heavy like something unanutaral is around. This boy looked like he didn't have a soul. Both of us goes to this school everytime we go near this area of the school the air feel's heavy but none of are friends belive's us. Whats should we do?
