I am someone who typically thinks very scientifically, but a few things that happened in my house and to other neighbors make me a skeptic. First of all ill give you some history i think is vital! We live in the midwest. When they were building my house they found 3 tombstones with no bodies. 

We are on old native grounds and have found arrow heads in places that make zero sense (ex: under a desk in the middle of the house). My sister and i have experienced the most. When this house was built i wasnt alive; It was just my mother and sister.

The first week of living there my sister saw a shadowy man in a cowboy hat with a dog. She was probably around 6 years old at the time and told mom about the man that watched the sleep. The next night someone was pounding at the door and violently shaking it to the point my mom called the neighbor to bring a gun to the front door. No one was there and there were no traces that anyone had been there. That was just the beginning. 

When i was born, the activity worsened. My dad and mom would see an old lady walking through the kitchen. Dad would see her entering, mom would see her leaving. One night on the baby monitor my mom heard an old womans voice go “oh, such a good baby” which led her to run into the room ready to fight whoever had entered the home. No one was there. 
We’ve had things fly off of the back of shelves and out of outlets before. One of these was a battery charger i had plugged in for my xbox. It flew across the room while me and a friend were on the couch gaming. The worst? A full large bottle of laundry detergent getting thrown at my head (~1yr ago?). Nothing else on that shelf moved. Not even the lighter alcohol bottles! 

Im only mentioning the most notable activity as theres been a lot over the years but it ended  when me and sis hit certain ages. When sis turned 10 the activity died down for a while. When i turned 10 it came to a full stop. We have since only gotten activity after big changes in the household. This next part is what happened yesterday evening and brought all of this back to mind.

My father isnt easy to disturb. We got back from a vacation not too long ago so we were doing some yard work when dad went to rinse out his wagon for hauling yard waste. Our neighbor has a first story window that’s directly across from our hose and her window is notably always fully closed (blinds and all). As he approached the window and started rinsing the wagon he turned around and saw something lift the blinds, look at him with one eye exposed, head tilted, then drop the blinds.

I was right around the corner and asked him if he was alright because he seemed off and he assured me he was fine. I didnt question any further since i just assumed he was tired. Today he asked my neighbor if anyone had been home and she asked why. He explained what had happened and told him that she wasnt home. On top of that, her dogs are so tiny that they cant even reach the window on their hind legs. She then went on to mention how she had started burning sage recently due to some weird activity. 

Her house was built around the same time but the original owners died when i was fairly young. Ever since then, its been a rental. Dad asked her why she was saging the house and she told him that her roomates wall mounted mirror was thrown across the room one day. She claims shes been experiencing some odd things and felt like she had to sage it to get it to stop. 

We’ve seen people in our neighborhood posting about weird stuff happening around their houses too but; today was one of the most forward appearances we have ever had. Im starting to question my beliefs on these things again and its really throwing me for a loop. I drew what my dad explained to me and will attach it to this thread. I really want all of this to be easily explainable. 

(Note: the tombs were moved to a mini graveyard thats a few houses away. They didnt want to move them too far from their possible resting place to be respectful.)

History of activity since i was a baby, now its suddenly back?
