Whenever I'm called into investigations for potential hauntings, we have to debunk a lot of things. We have an arhchitect on our team who can explain drafts and house settling noises. There are many other things we look for to disprove or prove the paranormal is at work in a house.
I've blogged before how a messy house causes bad energy and discord. Last week this article appeared in the Huffington Post along those lines, with a focus on poor air quality (which you can have if you don't change filters often in your heating and cooling systems, or if someone smokes in the house).

Purpose of this Blog
Rob Gutro is an author, paranormal investigator and medium with Inspired Ghost Tracking of Maryland. Since he was a child he could receive messages from ghosts or spirits (who have crossed over). *He wrote the books "Pets and the Afterlife," "Pets and the Afterlife 2," "Ghosts and Spirits" and "Lessons Learned from Talking to the Dead" to teach others how ghosts and Spirits communicate with the living and to give proof of the afterlife. As a scientist, he also provides some scientific explanations about how energy is the baseline for the afterlife and the medium that entities use to communicate.
