I've had many experiences with spirits. Most of them don't even bother me,they simply walk around,float though walls sometimes then are off. I'm guessing there just curious.But I also have experience the dark ones. At one time in my life I was having a really hard time and was slightly depressed. That was when they came around.I Began to study allot more about the paranormal and found out that theses spirits(the dark ones) Love to feed on your fear and energy;So its always good to stay positive and calm
