yes, i have experienced spirits. i am able to see and communicate with them. the effect it has on me depends on the spirit. sometimes i become very cold while other times i have become physically ill (this is a rare occurrance, so far). when a spirit wants to communicate, i can become very cold and even start to shake. certain spirits can have intense amounts of energy, which can effect the living in a number of different ways. being able to see and communicate with spirits has effected my life in both positive and negative ways. people have been cruel and accepting. you just never know how someone is going to react to it. spirits are very familiar to me. i deal with them on a daily basis. most have been pleasant and non-threatening. there have been some dark spirits/entities. you have to take the good with the bad. most everyone has encountered a spirit at some point in their lives. most just either don't want to admit it or try to explain it away. do not dismiss them. spirits are people, too, they have transitioned is all. you may have an ability that maybe you should look into.
