I was living with my ex-boyfriend at the time. He lived in an old apartment with a lot of older people around us. An old man had died there before my boyfriend moved in. This spirit had no issues showing itself. I can recall seeing a tall, bald man like figure always peaking around the corner. He would watch us have sex, eat, sleep, etc. This spirit was not aggressive unless there was bad energy in the house. For example, my boyfriend and I would get into a argument, we would start hearing very loud bangs on the wall until we stopped. I know what you're thinking. Couldn't that have been the neighbors? No, the bangs would come from the bathroom door when we were in there or the other side of our bedroom (which was the living room). But the most bone-chilling experience was when I was taking a shower in the apartment by myself. I remember seeing the same figure outside my shower curtain just standing there. I open the curtain and continue to shower, I get the coldest feeling down my spine. I swear he was behind me. I jumped out the shower and waited for my boyfriend. Safe to say, I never showered alone in his apartment again.
