Is my house haunted do you think

I always hear bangs and thuds when I am on my own, I've always been quite a gifted person when it comes to paranormal stuff. I'm only 17 so I'm not sure! I thought it was my imagination til 10 minutes ago. I was messing on my iPhone camera and taking pictures of my room in the dark with the flash on, and I kept seeing this white circle light moving quite fast, but I could only see it on the camera screen, not with my own eyes. Since I noticed it, my right shoulder has been freezing! I am so freaked!

That white circle your seeing is the pigment of your retina bouncing off your lens of your eye causing a mirror effect. Every time your eyes try to adjust there is some play with light when they try to adjust. It is nothing paranormal about it. I've had this happen to me as well when i'm doing the same thing in paranormal investigation. Its nothing to be concerned about. Just your eyes playing tricks on you is all. I should know, there is quite a bit i've seen that i have to sort out my self between what is real and what isn't. If i preserve something to be real too quickly. It becomes a problem.

As for your right shoulder, quick light flashes can effect brain activity and cause it to overload in some areas. Hence why flash bangs are so effective. Overload of the nervous system via sound and sight are good ways to temporarily paralyze someone or cause them to lose there balance and fall down.

You could be in the presence of a spirit. It is odd that your camera lens is the only thing that seems to be capturing this activity. If you wish to try and remove what you think is a spirit, start off by sprinkling salt on all windowsills and door steps. If the activity intensifies, burn a sage stick. It is more in depth in removing negative energy. However if the activity becomes violent, or seemingly out of control, contact your a spiritual leader to clense your home.
