I didn't check the tv due to the fact it was a somewhat common occurrence for it to turn on at random, even if the timing and the manner of it turning on and off rapidly was bizarre. When I check there was absolutely nothing wrong or disturbed other than a door that was locked became unlocked.
I have a very. Very. Very. Bad phobia of paranormal things. I'm not scared of much but anything that comes off as paranormal makes my knees shake. Hence why I didn't check the house at the time. It also came from a locked room that has no way in. No windows and an electric garage door that is extremely loud. Not to mention I was sitting 5 feet from the garage door. So I would have clearly heard any intrusion via the garage. As well as my nana had told me to leave if anything like that were to continue happening. Please explain to me how the dogs strange behaviour as well can be due to pests
