I do know spirits exist. I have had a spirit taunting me since 2007 I don't know who it is or what they want but they aren't there to do any harm or I would have been dead by now. They do make their presence known even though I can't see them. At first I thought it was just the bed so I went and bought a new bed and the same thing was still happening. At first I was scared shitless for the first year then after that I started ignoring whoever it is but they still kept up what they were doing. I'll have to invest in a spirit box someday and see if it picks anything up see if I can make some communication with whomever it is. I have lived in 3 different Apartments since 2007 and wherever I move to it follows along.
