actually dont think much of this thing la.. actually u dun have to try to find all clues that this is a non-human action... i mean its pointless... no one is harm rite? just that these "Good Brother" like to tease. IF it is this Good brother, i dun thk it meant harm to anyone.. i think he just like to teast around and scare ppl
Luckily no one is harm due to these..
Those what u shud afraid is those that are the real Evil or demon...
Or u can ask anyone who dare to play Ouija board in that room, TS.. but i hope no one try it cuz it might give that thing more power and u might be in danger
Actually anyone can do more investigation in this room.. try put some recorder and put it near the phone. put a video in that room for 24 hours or more..for more high-tech, u can use thermal video to capture any diff in heat..
and take some pictures near the phone at night or anywhere then go back home analyse any pic if u see any orb or any weird stuff. Ppl can try it to see if anything different .. like any faint voices.. but those who be an investigator.. must have real brave heart ... its not as easy as ppl think to be ghost investigator
