The ability to see spirits is a very controversial topic and rightfully so. Those who have an open mind will have a greater chance of being able to see a "spirit" than those who are skeptical. Skepticism kills all the possibility of seeing a spirit. Your mind controls whither or not you will be able to see them. If you do not believe in your mind that spirits can exist your mind won't show them to you. Personally, I believe spirits do indeed exist, but only to people who believe in them. I find it very hypocritical that many Christians down play the possibility of spirits and such when they believe in God. If you believe in something it then becomes real in your mind, therefor to any one who truly believes in spirits, will be able to see them. Perspective is everything. To those who don't believe in spirits and the afterlife that is your right,but I think it is a little out of line to poke fun at those who do.
