I'm 13 and I think I have some connection with "the other side". I was at my pastor's house with my two best friends for a sleepover. The three of us were sharing a bed (it was a sleepover with our whole youth group so there wasn't that much room for fifteen people to have their own bed). Then I just randomly woke up and when I looked to my left, I saw this girl whose skin was so pale it looked light blue, her hair was long and black and covered part of her face, she was wearing a white night gown and she was just staring at me. I was fully awake at the moment but at the same time I felt like I was sleeping. So it didn't fully register into my head that someone who I don't know, who randomly appears in my face, and who is I'm guessing a ghost or something is staring straight at me and I'm staring straight at her. Then being the idiotic person that I am, I just turned my head because it didn't bother me and quickly drifted off into sleep.
When I told one of my best friends about it, she asked me about her details and how she looked. It was scary because she knew exactly who I was talking about! She got every detail right from her dress all the way to her eyes! So can anyone explain this to me?
I see the exact same things in my room at night. I feel them and see them and hear them. The female spirit was probably hanging around you because she wanted to join you. I believe that she wanted to hang out with you so that she can feel less lonely.
I don't know what you should do other then set boundaries. That is the best advice I can give.:)
