We are Lutherans, and we are active in our church. About 30 years ago, we moved into a new home (we were the third owners). The neighbor across the street had occasionally seen someone looking out of the windows of our vacant house, and after we moved in, we (our whole family) saw an adult male human figure moving about, but it never spoke or threatened us in any way. One day, the lamp was alternating dim/bright and it bothered me, so I told "it" to stop that. It did stop. The figure also frightened a houseguest on one occasion. But after several years, the ghost just disappeared. We sold that house and moved out. The new owners never complained of anything unusual when we saw them later on. So, if this was an evil spirit, I'm wondering why it didn't ever try to frighten us.
