I also find that "claiming" the home as yours may often help. it's really as simple as just going to a place you feel the "energy" (like the BR) and telling them aloud that this is your home now, your family lives there, the time for them to be here is over and they need to please move on. say it firmly, but not unpleasantly and feel free to add whatever else you'd like
sometimes they dont mean us any harm, they just dont know they are scaring or bothering us.
House cleansing is also a good idea, and there are many things that may help in that arena,like smudging the home, blessing the home including all windows/doors/in and outs to the home/front walk way or porch. i even remember someone saying here that they use white chalk to put protective pentagrams on the walls or windows of their home~the chalk doesnt show on white paint so no one else even knows they are there! you could also do the same with blessed salt water with good results.
How do you feel about the possible energy? Does it feel negative to you or does it just unnerve you? (which is totally normal!!) It may not be a bad spirit per say (or it might, personally idk) it might even need a little shove in the right direction; ya never know
I wish you all the best in this~
