Is there a poltergeist in my house?

Hey guys, so i'm a 15 year old female. (turning 16) And, for the longest time i've believed my house was haunted.. i'd hear things, and not only hear, but see.. Such as i witnessed a candle stick fly across the room once, when one of my other friends were living with us at one point. (Reason i mention that is because i heard poltergeists feed off of energy, and she was a very troubled person) Anyhow, so i was out of the house for 2 weeks. I came back last night, my mom said NOTHING happened when i was gone. Last night i went to bed, and i had the feeling i was being watched, i seen a Shadow go by the hall and my rabbit freaked right out, he was stomping and throwing things ALL night. I could NOT sleep. Anyhow this morning my mom wakes me, and she's like.. "wanna hear something freaky?" So she tells me that last night she heard a woman's voice, so she assumed it was her phone and pressed end. Then all of a sudden her phone rings and she answers it, and it's 911 saying that she called them, she didn't say anything, she just dialed it.. For my moms phone there are many steps to call someone she would have had to press 7 buttons in total.. So i was a bit freaked out, and my mom also said she felt like she was being watched, and she felt as if someone was standing right around the corner constantly.. So when my mom told me this and she left i had a bit of an anxiety attack then all of a sudden, my motion censored alarm clock beeps.. For this thing to beep, you have to wave your hand directly over it. When it beeped i turned around, and nothing was around it. What do you guys think?
