Demon Creeping The Crap Out Of Me

I'm 14 and I believe I can sense presences of spirits, angels and demons. About a year ago, I began feeling this really strong presence in my room sometimes my parents' room. I feel it looking at me. Sometimes I get extremely overwhelmed and my heart rushes and I begin feeling really scared. Sometimes when I am laying in bed waiting for sleep, I feel this push on my bed. It keeps on repeating. And it gets stronger. It's like the demon is pushing the bed. I accualy hear the bed being pushed. That petrified me and I would sweat a lot. Sometimes I look, and the pushing stop. And it returns after I lay back in bed. Once, I was home alone. I was late at night so I went to sleep. Sometime around 3am, I awoke and my blanket was slightly hovering over me. I swear, I'M NOT LYING. Then I got up really fast and I heard someone running down the stairs. The blanket stopped hovering. I confused. I thought demons can't interact with humans phiscically. When I'm alone it gets worse. I used to hear movement downstairs, like furniture, and etc. I used to get really scared. By the way, I can speak to my guardian angel telepathically. She told me to ignore the demon when I sense the presence. Then all these things the demon did to me stopped. But I still today feel it dwelling in my house. Spirits don't scare me. They just observe my life. By the way, I sometimes see spirits and they disappear in a split second. Do you guys know what that is? When I see them, its like I'm looking at them with terrible eye sight. There is this other weird thing, I see bizzilions of dots floating everywhere. It looks exactly like when you use the old tv's and you turn to a channel with no network and it has this weird static sound and a weird screen. That's how it looks like. When I focus on them, they for designs. They are sometimes color ful. I'm also colorblind. My parents don't believe me. Does this have to do with seeing the spirits?
