I have never experienced this type of fear. One day I was having a peaceful bath away from the hustle and bustle, and I would like to say before I go on that my family was away shopping for my birthday, it was just me and the dog. Recently my favorite cousin in the world, Lilly, had passed away. This was devasting and so I was relaxing in the bath and the light turns off and I'm like oh its ok, the power probably went out but then the cold tap started turning on its own. My heart stopped. I screamed so loud, then I ran out of that bathroom just like that.
Later I came back into the room to check and the light was on again, I didn't know what the hell was going on, but I knew I was scared. A couple of hours later my family came back and I tried to tell them what happened and they didn't believe me. My family has never believed in this stuff but I definitely do now. The next day I was giving my dog a bath and the light gave out and exploded in a poof of smoke, the dog started jumping around then. He jumped out of the bath and was doing tricks as if Lilly was commanding him to, he only does tricks when someone asks him to, never just for fun.
I know you may think these are all just coincidences but the thing is that Lilly died because the light from her bathroom fell on her when she was home alone just like me. Sometimes when I'm in the bathroom the lights start flickering and I feel a shiver down my spine. Sometimes I just go in the bathroom just to feel her.
I can see why you would feel that way and draw comparisons between you and your cousins similar situations, being alone and the light blowing out and so on... It's ok to be scared but you have to believe that the same thing isn't going to happen to you.
I know how you feel when you lose someone close to you but I like to think that our loved ones are always with us.
