Ghost being disturbed?

I moved my furniture around in my room yesterday. I've always had a weird feeling something was in my room but nothing serious happened....I only Always got sleep paralysis. but last night first i heard something bang behind me beforee then i was on vc and i started hearing noises through the computer like it was like a deep voice every time i talked but idk if that was just a computer problem....but then it took my 10 mins to calm down THEN My tv spases out and goes to no signal then my brother fixed it thenn my brother left and a louder then ussual tick goes from my radiator thennn i was calm till something fell in my closet I RAN as fast as i can out into my parents room I slept on there floor cause i couldnt stay in there. i later found out it was my pillow at the top of the closet. it didnt bother me cause its morning but,...My picture just fell on the ground...it was hung up Pretty good....and idk if it was coincidence but it was right after i was joking around with my friend and i said it should get the **** out on a facebook chat....I'm 14 and sleep paralysis only has happened in MY room and it goes away when i go to sleep on my moms floor... and it never follows me? Please tell me if this is a ghost or not. No one thinks its a ghost and everyone says its in my head but i belive it is..My mom said no one has died on this property it was my grandfathers property and if it was someone it'd be him.
