I was babysitting for a family in the middle of the country one evening. They had no neighbours except one who was an older man that was completely off grid. It was two girls the oldest being about 4. They also had a dog and a cat. After i put both girls to bed the oldest of the two came out of her room asking for some water. We were standing in the kitchen that faced the back yard. There was a deck off a sliding door that the girl was standing at as i filled the water. She was looking off into the night and then looked at me pointing to the back of the property and asked, “whats that shadow out there?”. Concerned i brushed it off as maybe she saw a tree sway in the moonlight as it was super bright that night. That’s what i explained it to her as to calm myself down and to keep her from being scared. Next she asked me, “so the man shadow is trees?”, i nervously laughed and said “yup” to keep her from getting scared. After that i put her back to bed and proceeded to forget about it and watch a movie on my phone on the couch. After a little bit i got a text from my mom that was about an hour and a half away telling me to go outside as there was northern lights. Too scared to go out back from the previous convo i had with the little girl i went out to the front where they had a porch light. The dog was close behind me and as soon as i cracked the front door the dog went absolutely insane barking and growling. The parents had mentioned that she sometimes does this , and if it were to happen to put her out back and she has a collar on that prevents her from leaving the yard and she should calm down. When i let the dog out she bolted to the back of the property where the littler girl had previously pointed and had been staring at all while barking like crazy and growling. After a while she came back to the house and instead of being calmed down she sat at the stairs of the deck looking out into the same direction in a continuous growl and bark. After letting this go on for about 30 mins I brought her back inside and put her in her crate in a dark room with a blanket covering it. I sat back on the couch and the dog continued to be agitated in till i left and I could hear her pacing and continuing to growl. I dont think it was a person or a living one at least because of how far we were out into the country. After that i had to go home to a big dark house and spend my first night alone as my parents were away. Cant say I slept much
