Is My room Haunted??

I hear this growling somtimes around the house..once i was locked out and i was ringing the doorbell thinking my sister was home and i heard growling and it didnt stop. This other time i walked into the kitchen and i heard it and ran out of my house. In the early mornings when i get ready to go to school i always hear snoring in one corner... and whenever i walk into my room or my brothers there is always this uneasy feeling and like im being watched constantly...Help Me i dont know what to think!!!

Just really freaky!!
