:) First of all I have a best friend who keeps hearing 5 knocks on a wall in her house the same wall every time.So far 3 of the 5 people who live there have heard it and it only happens about once everyother day.We have searched the house high and low looking for creatures,bushes,vines, humans anything that could be making these noises.. And found nothing.My friend is terrified and can't stand it anymore we really need to know what these noises are.My cousin said when she was in high school she stayed in that home with a friend and heard some knocking two times on the same wall. I haven't decided weather or not that's the tructh or not yet.. I have also heard from one pearson that it could be bad plumming but we had someone come out and look at that and he didn't see anything wrong with it.. They have added brick underpinning all the way around the house to ensure nothing can get under there.She just needs piece of mind and I don't know what to tell her.If u have any suggestion please let me know...

It may just be a phenomania. I don't know the name of it or how to explain it, but it is basically like if somebody that lived there always knocked on that wall and some type of
(I think it is called something like electromagnetic phenomania) where the knocking can still exist.
They say that the Gettysburg battle has this type of phenomania.

You may have a mischievous ghost hanging around her property. This can be easy to dispel or hard depending on just how entrenched it is.

I wonder?? Ghosts just seem so far out there to me .Kinds like not real but I guess if they are harmless I can handle that.Are all ghosts harmless??

There are the poltergist ghosts but you would know by now if it were that cause they don't play around.
