Paranormal activity or is there a scientific explanation?

It sounds to me that you could have a spirit in your home and this is how they are making you aware that they are there with you.Keep an eye on your dogs behavior,as animals are very highly perceptive to any any spiritual activity.Also try to notice any temperature drops in the room,such as cold spots,this is how entity's draw energy to manifest themselves.It could be a spirit that once lived on the land where your home is or if you aren't the sole owners of the home it could be a spirit that lived in the home at one time.The only way to know for sure is to get a tape recorder running and try to pick up any evp's that are going on that is below the level of human hearing,you can also ask questions while running the tape,such as is there a spirit present,what is your name and why are you here.You can also shoot some photos with a digital camera and see if you pick up anything on film.These are the methods that paranormal investigators use to try and debunk and doent anything occurring,This is the only way to get to the bottom of what is happening around the home,you can always command the presence to leave in Jesus Christ's name and see if it makes a difference.Hope this is of some help,if you come up with any paranormal findings,please come back to this section and share them with all of us paranormal fans.
