Something In The Bedroom

I was informed by my cousin that is visiting with us that she does not like our bedroom. I asked her why and she said it is just weird and freaks her out. I asked her why and she went on to explain that something was on the bottom of the bed with her,then she told me about how your hair on your body stands up when something is around that scares or touches you , you can't see and also about hearing banging, but not knowing where it was coming from. Our bedroom is one of the most active places in the house and who knows what will go on now.
