Do not be alarmed but it is most likely that you do have "someone" traipsing around your home. I suggest that you do a lot of positive things like singing, dancing, laughing clapping and tell them this is not their home. If you are able to 'smudge' your house with sage and say a prayer to "god" and them. Let them know they no longer need to be in confusion or pain. Their home is with God, the Angels and their family and friends who have passed, this is a beautiful and safe space and that they are welcome there with no fear of judgement. Tell then that God and the Angels are here and ready to take them back "home" now.
You may need to do this several times if they are stubborn. Call upon your angels and their angels to take them home.
When you smudge, do this in a clockwise from the front door and through all areas, even cabinets and closets. It's stinky but it helps! Then remember to talk to the "someone" and remind them that this is your house, it is nice that they visited but greater that they go home.
Tell God and angels that you are cleaning the house of any negativity and people that are not invited. Then invite in all Love, Peace and Light to fill your home and everywhere you and your family go.
Do not ever allow Ouija in your home!! It can bring in all sorts, good and bad. Do not worry about Tarot, etc. these are just tools that help you understand life. Bless them and let them bring in only the truth and the light. Remind any practitioners of this in your home to do the same. If not, they are not welcome. Only truth, peace love and light fills your home!!
