Protecting your Home from Spiritual Darkness (demons-ghosts)
Very good point. An awful lot of turnover occurs in hotel & motel rooms. A lot of sex, pornography, hate, abuse and violence goes on in these rooms. People even set up pagan shrines in these rooms sometimes. Also, many pagans stay in these rooms. They are "evil magnets". Every Christian has the power to "discern" what is going on around them "spiritually". They only need to learn to listen to God. This "discernment" (often just a strange but powerful feeling of dread like you encountered) could be a warning from God. None of this. Including speaking the (1-way) prayer below, is not to be confused with either spiritualism (attempting to communicate with spirits) or spiritism, which is forbidden in Scripture...
If people would pay more attention to their spiritual surroundings and make corrections - they could live happier and healthier lives.
You are right! Pleading the blood of the Lamb of God is the way to go--always. A prayer such as the following spoken out loud will usually work; "I am a child of the Most High God. Because of the blood that Jesus shed for me, I have been saved, and my sins have been forgiven. In the holy name of my Lord, Jesus of Nazareth, I command all demons and evil to leave."
