Having lived in homes from time to time where there are negative imprints and energies over the years, as well as having gone into homes to assist where this is a problem, I have to disagree with the statement about not paying attention to it.
One home that I lived in from 2005 to 2008, for example, had a wonderful "air" to it when my now ex-husband and I moved in. However, it did not stay that way for long and once my children and his children were present in the home things rapidly changed.
To ignore a negative situation by not acknowledging it does not equate as what one would do with a small child throwing a temper tantrum. It's more like ignoring cancer and hoping it will go away on it's own without treatment.
Having small children or even grade school aged children or teens is going to be a concern; especially for their safety.
Having come into this discussion at this "late hour", one thing you must ask yourself is 1) If you rent the home, is it worth fighting for to stay and 2) If you own the home are you again, willing to either find a way to cleanse the home or to find a way to make peace with whatever is there.
If your answer is to fight for your home, I would advise doing so when the children are not present. Perhaps they can stay the night or weekend at a family member's house or a friend's house for a sleep over.
Understand that some things just won't be moved; regardless of what you try. Other times, you can be successful in the cleansing but realize that you may need to repeat it from time to time to ensure keeping the peace.
If it is a negative imprint that is there and your home is newer, there is a good chance that the location is tainted. Whatever happened long ago on that property is going to probably stay there. A scar if you will in a dimensional fold. Unfortunately, it's not like having plastic surgery to remove a scar on your body.
My advice to you is first, keep a positive influence around the house. Play positive music, watch movies that will induce laughter, be affectionate with your family and show love. If you are having marital issues, find a way to "talk" and "discuss" things rather than fight about it. Negative imprints will feed off discourse and unhappiness; just as a cancer will metastasize into other areas of the body. It will spread like a disease if your family has a negative flux.
Document times, dates and what happens. For example: On Jan. 3, at 2:46 am, you were awakened by cabinets banging in the kitchen. Upon investigation, everyone in the house was sleeping and there was no reasonable explanation for the event.
If you have smaller children, have they "found" an "invisible playmate"? If so, watch this and document this also. While it is normal for children to have unseen friends via the imagination, there are documented cases where children have befriended the spirit(s). And, while it may start off as innocent, it could very well change to something else. So pay attention if this is the case.
If you're hearing things, or unexplained things are happening, talk to it as if you were talking to me or someone else that was doing something that was not acceptable to you in your home. The key word is TALK. Don't instigate or patronize. Make it clear that you are aware of their presence and you would appreciate it if they did not "slam the kitchen cabinet" or "turn off the lights while someone was in the shower" or "I do not approve of your scaring my children". Often a peace can be made just by making it clear that this is your home now and this is what is not acceptable.
If you choose to do a cleansing, please refer to the Cleansing through Smudging article. It is a step by step of how to cleanse your person as well as your home and property.
Finally, the most important thing is to not show fear to it. If you need to vent or talk about it, do that part outside of the home. Remember negativity breeds negativity.
I hope this has helped some and I wish you the very best with your situation.
