If you live somewhere that you feel uncomfortable, your animals aren't happy and stay in a constant state of alertness, or you've had some unexplainable runs of bad happenings, you might want to consider blessing the property, the home, all buildings, animals, people and even vehicles.
I use a Christian blessing because my beliefs are more Judeo-Christian than anything else, but you can use a blessing from whatever belief system you have. The power comes from belief, not any particular religion. As long as you believe in the power of what you're doing to bless and cleanse, it should work. There are no 'wrong' blessings, as long as you're calling on the power of good and not evil.
I'm a firm believer that everyone has some ability to sense different dimensions and those who inhabit them. Not all gifts are the same though, and they can be compromised by disbelief or fear.
