Disclaimer:  these are my opinions and I don’t wanna offend anybody. I’m religious. Believe what you believe. I’m just expressing what I’ve found in my own life.

As a Southern Baptist, this thread has been very interesting to read. My dad is so into this kind of stuff, so I’d love to chip in on my own theories.

Personally, I don’t believe in ghosts, but I do believe that paranormal activity is caused by angelic beings, be that angels or demons. I’ve never heard anything about colors of angels, and I can’t speak to the validity of that because I’m uninformed and I haven’t seen any of that in Scripture, but upon reading this thread, I remembered something that my high school English teacher said one day after we read a story in our literature class about a man on his death bed who spent his life trying to repay a debt. In the story, this man lay on his deathbed, looking out the window and gazing at the magnificent ship coming to take him home. The other man who the debtor had spent his life laboring to repay walked in moments before his death, and was shaken to the core because there was no ship. My English teacher, on the verge of tears, said, “This story gets me every time I read it, because I’ve heard stories of Christians who saw angels coming to take them home and stories of atheists who saw demons coming for them.” And then she dismissed us to go to our next class.

My dad always goes on about electromagnetic energy, and how some people are more sensitive to it than others. My family has always been more sensitive to it, and because it’s highly possible that angelic beings manipulate EM energy, those who are more sensitive to it are probably more likely to sense their presence. Although, because I’m religious, I believe that if you’ve accepted Christ and have His Spirit with you, obviously you’re gonna sense when something like that is present. I’ll get a sick feeling in my stomach sometimes passing certain places in a town nearby where a certain religious group meets that I’m not gonna mention because I don’t wanna offend anybody, and my parents will feel it at the same time. I don’t think that’s a coincidence. It’s interesting to think about.
