This happened to me when I was in middle school. I used to be scared of the paranormal/unknown so I never really dove into it when I was younger because it would keep me up at night.
I remember being scared to shower with the door closed if nobody was home. This day I was home alone. I turned on the water and jumped into the shower. It was still daylight, my mom and stepdad weren't home from work, my siblings either were in sports or with friends.
My shower is downstairs. If you are in the shower and turn your head to the right, the toilet, sink, mirror and door are right there. Suddenly I got this urge to look towards the right, towards the open door when I saw a half body apparition from the shoulders up. She had tight blonde curls and blood all over her face. I just stared at her, wide-eyed, not knowing how to react. We made eye contact and then she stuck her tongue out at me and disappeared. I was so shaken I jumped out of the shower, dried off and ran upstairs. I never saw her again and that was just the beginning.
I used to sleep with my cat every night. I was scared of sleeping alone and he would bring me comfort and soothe me. One night everyone was getting ready for bed when I left my room to go downstairs to get my cat. I picked him up, heading back up the stairs. I never liked using the bathroom upstairs. All my sibilings used it but it always had this weird feeling to me.
The light in the hallway was on, so was the bathroom light. I got this tingle that started in the back of my neck that shot to the rest of my body. I got this feeling I needed to look into the bathroom. When I did, I saw an apparition of a teenage girl who looked like me: skinny, tall and sandy blonde hair but her eyes were blue, mine are hazel. She was wearing a grey sweatshirt, blue jeans and her hair was in a ponytail. She leaned over like she was picking up something she dropped. When she saw me she was shocked, like I caught her off guard. She looked surprised and then disappeared very fast. All that was left was a faint white mist.
