We just bought a house at the end of March and we have been having some odd things happening. A couple days after we moved in my kids windows were open the next morning after we know we shut them before bed. The screens were still in place and the back gate leading to their windows was still latched.
My middle son who is 14 started hearing noises in hall at night. A little girl counting, she counted to eight and stopped and someone walking in the hall.
I have a pocket door for my bathroom in my room, I went in my room to use the bathroom to my knowledge no one was home. My husband had left for work early that morning, my oldest was at a friends and I had just gotten back from taking the other two to school. The door was shut and I could see the light was on from the cracks. I tried to slide it open but it was locked, I knocked and asked if someone was in there, no response. Then I panicked a little thinking my older son had come home and something happened like he slipped and hit his head. I called his name, no response. So I went to get a flat object to turn the lock. I opened the door and nobody was there. This experience bothered me because I used the bathroom right before I went out the door and I know I didn't shut the door and I definitely did not lock it from the outside.
The next experience was getting up for work, 4:45am, my bedroom door is straight down from my youngest son's room, and I could see this black foggy mass passing in front of his toy drawers. It's one of those rubbermaid plastic drawers you get from walmart. It was about three feet in height and no form at all, and it moved super slow. I just stood there and watched it go through and it either disappeared as it went into the wall or it went through to the other room. I look for it all the time now but haven't seen it since.
The next event I am having a lot of trouble wrapping my brain around. I was laying on my bed paying Bills, I had my phone, the bills, and a pen. I was on the phone with the automated system and realized I needed the checkbook. The checkbook was in the file cabinet on the other side of the room. I got up off the bed with only my phone in my hand and walked across the room. I was almost to the cabinet when the pen that I left on the bed hit me in the back of the head. I turned and looked at the pen that had fallen at my feet and asked out loud, "Did you just hit me with a pen? That's not cool!" I measured it, the pen flew about 12 to 13 feet. It didn't hurt but it was a solid hit. I don't understand this at all, it boggles my mind!
The next thing may be a live human person. I was making my coffee in the kitchen at 5am. I use only the light under the microwave because the main kitchen light is too bright before coffee. Coffee is done and I am shaking my creamer bottle and I look out the kitchen window to see a man in my driveway a few feet away looking at me. I couldn't make out facial features but it was still dark, he was very small and kind of felt more like 12 year old size and all in black. We both stood there for a few seconds staring at each other, he didn't move a muscle. Then I decided I should catch him. I bolted for the door coffee creamer still in hand and ran out, nothing nowhere, not a sound of running feet either. I told my husband about the man and we decided to get a ring doorbell for a little more security. I am going to assume he was not a ghost because it's the live ones you really have to watch out for, but there is something about the encounter that just doesn't feel right, I don't know if it was the way he looked, his size, I'm just not sure.
The last event my son told me about this morning. He was laying in bed last night, and his closet door which was open about two feet closed. It is the type that slide. He told me, on a previous occasion it opened and then closed about the same distance. I checked the doors and they don't slide super easy so I don't believe it to be gravity, wind currents, or anything like that, I had to use some pressure to make them move.
So we have lived here about a month and a half and I am wondering what's going on, we did have a little girls disembodied voice at the other house, she said hello and mom to me, but I don't know if it's the same girl that was counting, and maybe she followed us. I don't feel threatened at all, but I would like to know who is here.
The whatever standing atop of kiba's death site almost seems like a taunt to me, and that is serious. The black masses themselves are concerning. What's more, all souls, kids or not, need to move on. In many religions, this life is thought of as the true death, and holding onto it unnecessarily is unhealthy. Helping a child to move on isn't hurting them, it's assisting them in a way they can't do themselves. The next life isn't something to be feared; I've been a lucid dreamer all my life and have experienced blindness, and I've seen how the next step looked to me and some others. It is not something to be feared (unless you're bad) and sending an innocent there isn't cruelty, it's kindness. To be at peace is a gift, and giving that gift to a child who has lost all close kin (assuming it's a more antiquated ghost) is love. It's what I'd want for any child of mine if they passed: I'd want them to have a helping hand and to move beyond this veil of tears.
If they don't accept that, then they are more likely using the ruse of an innocent to get something from you, and my tag team theory becomes more relevant. I appreciate you sharing kiba's experience as it gives more context to the situation; for me it causes an alarm. I meant to ask this yesterday, but have you seen the little girl or only heard her? What clothes was she wearing? I understand your husband is more of a skeptic, but given the level of activity it isn't my concern: these beings could be avoiding him on purpose to keep you there as long as possible.
If you extend the tag team theory to the members of your household and think of them in terms of biological analogies, i.e. Predator-prey, and assume normal behavioral patterns apply (i.e. Sociopathy, narcissism, empathy, apathy, etc) then analyze the situation as rationally as possible. What does poltergeist activity feed? Why and how does it play into your daily life? Why would it appear to you and one of your children but not the other people in your family? If the child is good and leaves, what else could happen? If the child refuses to move on, is there a rational/reasonable reason why they would do so? And on a serious note, that mass taunting you on a death site drew you out of your house in the dark and you knew it was potential danger and you seem quite rational and sane; how would that play out if it happened to other members of your family? Was it the same son who has experienced this event that discovered kiba? You don't have to answer those questions to me or anyone, just think about them and how/if they apply.
I understand this is traumatic; I know mega trauma, and have never lived without the paranormal and/or death entering the situation (not in a single house I've lived in, and it's been about 8 thus far). I know how icky this feels, and I know when you're in danger from things you can't see it feels a bit crazy, and it feels better to ignore than understand/engage (that can be a valid survival strategy but it doesn't seem to work here). The poltergeist activity/energy manifestation does worry me, especially with a middle schooler, and I'm glad you're looking into cleansings.
If you want to know more about the land (and you might need to to effectively cleanse) then look up the deeds, go to the local historical society: not everything is on Wikipedia or google. I'm sure your town kept some kind of records, and sites like ancestry.com keep those records, and can also be used when all googles fail. You can also look into census records: someone could've disappeared from the household and not have been reported as missing, especially if the parent was responsible (accident or abuse, both would've been hard to say for that individual). Records also get lost in fires and floods, so federal records can help fill in the blanks.
Last question: is it possible that kiba was being fed off of, and was too lethargic to get out of the way? Cats don't take humanoid forms generally, and that piece of the puzzle is a point of concern. Kiba could've been a warm up; what is next? I hope I'm wrong about that, really I do, but after watching my own cat battle a demon I've stopped ruling things out. Please note I ask questions not to get answers but to help you think rationally, and they're more like a prompt than something I need an answer to: to me these are questions you might need to answer before being able to fully deal with these situations in order to protect your family. My priority is your safety and the safety of your family, be they furry or humans, it's why my concern on this site isn't people making things up but people who genuinely need help.
A warning: beings that are negative don't want to be cleansed, they don't want to leave, and no matter how necessary a cleansing if it's not done effectively can irritate a spirit, so if you struggle with it find someone with more experience. I mean, from a spirits perspective it's a pendulum that swung too quick, and it can be thought of as addictive behavior: an addict can struggle to be clean even if it's what they need. Just things to think about, no requirements to respond in one fashion or another. Do what's right for you and those you love.
