Is a spirit able to cling to a person..?

My cats always stand guard in doorways of the rooms I’m in. And they follow me around all the time. If I’m relaxing on the couch they come over to me to check if I’m OK. At least I think that’s why. They look at me with wide eyes, then they smell my face and then they blink and purr. Weird little furballs. Hahah.
Cats and Negative energy protection
 
I think you get this gift from your mother. But has she seen the same things as you growing up? Trying to figure if this is attached to you or your bloodline.

My mom says she has a feeling whatever is around her, is her grandfather. She said she feels safe whenever she notices a presence. And she also recognize it as the same energy every time. It’s never anything aggressive or abusive about it. At least not that she has told me. But once I mentioned to her about feeling weight on top of me as I was going to sleep, and she said something about me telling her that many years ago. I can’t remember telling her that so it has to be a very long time ago.
