I was recently asked the question, "I wonder why when some people get touched by a spirit, sometimes it is associated with an ice cold feeling and other times not?". Of course nobody knows the answer to this for sure, but my theory is that there are two different types of touching. The first type is that the spirit is actually present right next to you and touching you, which creates an ice cold feeling since it is drawing energy (heat) from the atmosphere in order to sustain itself. The other type would be just the sensation of being touched (without the coldness) due to your brain being subjected to high levels of EMF, which could be either man-made or spirit induced. High levels of EMF can make you feel like you're being touched by essentially "shortcircuiting" or interfering with our brainwaves due to the high levels of EMF present. If spirit induced, this would likely be from a portal (some people call them wormholes) opening up that allows the spirit world (another dimension) that consists of pure energy to manipulate things in our world (dimension). I think portals (wormholes) can only exist for short periods of time but when they are open, it creates a tunnel between the two dimensions where we can interact with each other for short periods of time. I'd like to know your thoughts and/or theories on this if you have one. I always enjoy hearing other people's perspectives and ideas on this subject.
