The majority of people who have paranormal activity in their home but are unaware of ……..the Lurker!
I have found Lurker spirits at 75% of spirit removals/investigations that I have ever been at. They are located in the back of closets, furnace rooms, alcoves, and corners of rooms.

They love basements with laundry rooms and furnaces!
There is usually a hierarchy of spirits assembled in someone who has a home that is active: dominant or aggressive spirits, secondary or submissive spirits, and last, Lurkers. It’s extremely difficult for most people living in an actively haunted atmosphere to pick up on Lurker spirits.
They are very still, quiet and produce virtually no activity at all. They are as their name defines them – basically lurking in your home. Lurkers bear no ill will; and they also have nothing positive to contribute. When I come across them, they are incredibly embarrassed and even apologetic for being caught there.
They’re usually the last spirit I find as they are trying to fade into the woodwork (or other dimension) and become even more invisible and undetectable. As far as clearing them, all the ones I have encountered have no trouble leaving the home immediately and crossing over as quick as they can.
WHY are they even there?????? you ask. Well, they are just spirits that mad the decision to stay here on our plane for awhile so they can just “watch”. Watch everyday living, parties, celebrations, arguments, and just mundane stuff.
