There is a black shadow seen by myself two sons, and my boyfriend several times, my cats act funny, the shadow runs from my boyfriend usually tries to be around me mostly and secondly my oldest son, should we be worried are we in danger

Hould we fear this presence or is it friendly

It's a shadow.

Since this has been seen by multiple people many times and the animals (who are naturally psychic) See it and respond I would say your claim to have something spirit like in your home is correct and seems at this time not to be anything to worry about. Word of caution however!!!

Do not treat it like a human, a friend, part of the family or give it a name. Defendantly NEVER EVER try to use an Ouija board or any other communication device to talk to it or ask it to appear for you. This can lead to something horribly bad because your asking an entity (that you don't know it's true nature) to just come on in! It's like asking someone over the internet that you have never met, seen or personally talked to.. to come to dinner and by the way, you gave them the keys to your house. Lol

I hope I have not scared you because it seems your family is safe , and remember that spirits are just people who have no bodies anymore and want to live with you ! Lol. Hope this helps
