what does my dream mean?

(I know its long but please read it all.) Ok well I keep haveing differnt dreams but they all have the same theme. They all start in differnt places but hey are all really big and filled with people. I’ll be talking to 1 person then go to a small differnt room. Once I leave the small room I cant find the big room again and I cant find anyone. I start to panic (which is weird because I dont panic easily) then I hear this wisper voice calling my name and it gets really dark. as the voice get closer its like a blinding light then I feel a little hand in mine (its like the hand of maybe a 3 year old’s would feel) The little girl always says its ok Then I walk with her to a differnt room that is in my house. I always ask her where the people went but she isnt there. I know everybody in the big group of people but I dont know the little girl. I will go to my room and start crying because im scared and it will get dark again. I hear the little girl screaming help I try to get up but im stuck. Then I cant see at all because its so dark but I feel this big hand on my arm then I feel sharp cold meatal on my arm and a man’s voice says you took her from me. Now neither you or her can live. I think hes talking about the little girl. I feel a knife cutting me then I hear the little girl screaming my name saying help. Then I see a really big knife in the air caught but a glare on the light with a big hand on it. I try to scream but I cant. I wake up after that but I feel like I can still hear the little girl’s wisper saying its ok. I have started sleeping with a light on in my room but its not helping. Please help!
