I have lived with the paranormal the majority of my life. As a Sensitive and Empath and Investigator, I've had my share of experiences with the paranormal. However, for those who may be experiencing things they cannot explain or feel that there is a spirit (or more) in their home, I will try to give a lending hand.
First, one must keep in mind that regardless of where you live - a home, apartment, mobile home, etc.; all dwellings have their own sounds and idiosyncrasies.
