As empaths and Lightworkers we shine very brightly to those in the spirit realm. I have friends here at the EC who channel angels and they have been told that we are like beacons of bright light to those who are sticking around this frequency. It is possible that you are attracting people who have no physical body and are a bit confused as to their status. I would like to ask you a few questions. Does the room get cold when this happens ? Does this entity feel threatening or angry ? Does this entity feel loving or perhaps confused like it wants to ask you a question ? Is this a new house and if it isn't do you know anything about its history? Do you have unfinished business with someone close to you who has passed? These are all questions that will help us figure out this situation together.
I am also including a link to the topic of Archangels.
I suggest that you ask for the help of Azrael and Michael. Azrael will help this person to cross over into the Light and Michael is an excellent protector. I don't think that you have anything to fear at the moment as it seems to me, from what you have described, that it is someone who wishes to get your attention. From my own experience I know that when this happens for the first time that it can be a bit disconcerting and a little scary. However, I feel that if it was a something to beware of the person would have FELT dark and the intentions to frighten you would have been very strong. You can surround yourself with Light energy by bringing in angels to protect you and to help this person with whatever is troubling them. When some people cross over they stick around as they are very confused that no one can see them. When we leave our bodies we are still very much alive, but no one can see us. We are vibrating on a higher level and our molecules are much more dispersed. It is like the difference between ice and a light mist. Both are water, but in different states.
I hope that I have been of some help to you and if you wish to chat more please feel free to contact me.
Throw some love into the wind.
