After decades of helping folks in haunted homes who are uncomfortable with the activity, I learned some very effective basics and it all can be explained by quantum physics.

I am going to give you some interesting examples of what you will use to reinstate your control - 

People who see shadow people figures report similar situations. First, they see the shadow figure out of the corner of their eye, turn to focus on it, and it disappears or startles as if not expecting you to see it and it races away. 

The more you chase after Bigfoot to catch a glimpse or gather some photographic proof, the harder the task becomes. It's as if they can feel your intent upon them, your focus on them specifically.

Now, let's look at this video and I'll tell you what you need to do. 

Now, in your home, I suggest you lay out a spiral notebook on the counter. When a ghostly type of occurrence happens, write down the activity, time and date, other witnesses, weather conditions, any emotional changes among family such as recent arguments. 

Over time, you will find yourself excited when you encounter phenomenon instead of being scared. You go to your notebook and narc on the activity. The control goes to you. The very fact you are searching for activity and documenting it makes it quiet down. When you focus your attention on it, it ceases.

I will give you an example. As a kid, growing up in a Civil War Hospital home ("Aspen Grove") in Fairfax, Virginia, I started to note the strange patterns of activity. Someone moved in or someone moved out and things changed. If there were arguments between my sisters who were 10 months apart, a family member falling ill, and other scenarios, activity changed. Sometimes, it went quiet for periods of time and that made me start observing it and wondering what was causing the quiet. 

The more I spent my days studying it, it quieted more.

The one thing I do know about hauntings is the occupants of the building are crucial to the degree and types of activity. Right there, it tells me we are part of the haunting, perhaps an attractant, a catalyst, or a curiosity. Our very study of it alerts the activity it is being observed. When our cognition shifts to one of power, the activity reacts.
